This is all very novel because in the relatively long history of humans sticking stuff in geostationary orbit, not once until 2020 had any sort of mission gone out to geostationary and intentionally grappled or docked with another satellite.
There's a tendency for such experimental servicing missions (e.g DARPA Orbital Express) to take place in lower orbits, along with all the crewed space station docking and shuttle servicing missions. LEO is cheaper for servicing demonstrations, more human-friendly and also where the Hubble Space Telescope that took a fair bit of servicing happens to be based. But for the robotics, sufficiently advanced autonomy for the latency not to be a major issue is also important.

One of the things that people who don't pay attention to space based infrastructure find odd, if you tell them, is that in the entire history of manned spaceflight no human has ever gone to geostationary orbit.
The Apollo (and Artemis II) astronauts went through GEO inside a metal capsule going as fast as they could.

from other sources If I'm reading things right, one estimate of a round trip to mars would be 1000 millisieverts, which is considerable, the maximum allowed annual dose for a US radiation industry worker is 50mSv.
That's quite a who's who of public-private partnership. It's fascinating to watch these commercial space industries develop in real-time.

Outside of GEO, nobody in the public really knows what the X-37 does when it's in orbit, but one of the theories I have seen thrown around is that it's capable of approaching and inspecting other things in LEO, or theoretically even grabbing or manipulating one in some way.
Any service functions of existing equipment would depend on charge interface or communications functions that are not exposed or standardized.
It will make a good season to practice kinetic adjustments until the fleets start shipping terminals for Astromech droids.
Robots get the best jobs...

Congratulations on the launch.
I grew up in the middle of nowhere Virginia. Like many of you I was a nerd, and I had no outlet for that nerd-dom until I spent all summer working for money to buy a C64. I taught myself assembly, and was a high school intern at NASA Langley where I learned about parallel processing, was introduced to the idea that people would actually pay you money to program computers, and had a tour of their space robotics lab.
When I went to college the guy two doors down from me in the dorm decided he wanted to build a robot, and he recruited me because I knew how to code. We spent freshman year working on a six-legged frame walker which we dreamed would explore Mars someday (this was in the late 1980s, long before the first Mars rover). It didn't work for crap -- the late 1980s were a disaster for makers, we had to source everything from the hardware store or Radio Shack. It was also the most amazing thing I'd ever done, and from then on I was an aspiring space roboticist.
I managed to not fail out, but it was close.
I went to grad school at the University of Maryland's Space Systems Lab under Dave Akin ("Akin's Laws of Spacecraft Design"), where I learned control theory and a ton of hands-on skills and got to scuba dive supporting the development of Ranger, which could have been the first US satellite servicer except we could never find a launch for it. I graduated with a PhD in aerospace engineering in 2003, and got hired by NRL, where I worked on RSGS.
Just following your dialogue here enforces why I love HN comments x
Since the mission is designed to attach one and then leave to go to another satellite that needs servicing?
"Since the mission is designed to attach one and then leave to go to another satellite that needs servicing?"
Yes.
Too complicated for disassembly. But totally valid for modification.
