I don't want to push this in absurdum but generating files on all platforms might be difficult and puts extra requirement on the build environment.
That said we should have the tools to and instructions on how to generate all included files. I'm not sure that's true now.

Storing generated files in source control makes maintenance and patch review much harder and puts extra requirements on us to keep things in sync. I'd rather the computer do the extra work :)

We store C files and require a compiler, where we could just store the compiled .o files in source control. To me this is much the same thing.

Balint and Jörg and I discussed that we would eventually like to remove the ASN.1 generated source from git as well, and make that a standard part of the build process.
