I don’t know much about the internals of ATC, but my understanding is that the routing computer/algorithm uses the information to display to ATC options for routing and to generate your initial routing?
In other words, I don’t think the controller is sitting there “oh, this guy can do S2, let me give him a T-route” or whatever, the codes I assume are translated into information the controller can actually use (probably based on the tech level of the facility, I think some facilities are getting new equipment and software upgrades).
I get a lot of this information from the Opposing Bases podcast, which is great source of information, with real world IFR content without “product placement” or lots of filler.
On another note, if you configure all your info in 1800wxbrief.com, it will text your route to you when you file, and if it changes before you fly, you can EasyAmend the changes. Then, when you are ready to pick up your clearance, you are much more likely to get “as filed”. I thought this was pretty handy, and speeds up the clearance delivery process.
