Yes you can put in the work and zip a bunch of libraries up into your own home-brew framework. But I doubt it's time worth spent for most teams.

I think that actually depends on the programming language. With golang, such a task is much harder because integration is more errorprone and requires more plumbing, e.g. due to missing generics (until recently).

For other languages that is different though.
