The kernel version from git is part of the Release: field in the .spec.

It wouldn't - kernel-default-base.spec is separate from kernel-default.spec

Yes, that's cleaner.

TW does not have rebuild=transient/direct enabled, this is intentional.

That might work as well, but would require special configuration everywhere...

The current design of a split kernel-default-base.spec has multiple issues:
- Needs to be handled separately for maintenance submissions
- Is missing debuginfo and debugsources
- This rebuild issue
