Please remove amdgcn-tools-19. It is for llvm 19 but llvm-toolchain-19
has been removed from Testing and will not be included in Debian 14.

The default llvm in Debian Unstable is 21. (Ubuntu 26.10's default is 22).

amdgcn-tools-21 is built on more architectures than amdgcn-tools-19.

I have seen requests from the maintainer for other packages to be kept
in Unstable to somehow simplify getting updates into Debian Stable.
This isn't a requirement of the Debian Stable Release Team and I think
services like debusine are adequate in most cases for doing build
tests.

Thank you,
Jeremy Bícha
