Bug#1068961: llvm-toolchain-18: block migration to testing: to many llvm-toolchain versions in testing

[Sebastian Ramacher]

Source: llvm-toolchain-18
Version: 1:18.1.3-1
Severity: serious
X-Debbugs-Cc: sramacher at debian.org, debian-release at lists.debian.org

Currently we we have llvm-toolchain-{14,15,16,17} in testing whereas RC
bugs in the verious versions of llvm-toolchain do not get addressed:

#1067005 in llvm-toolchain-18
#1068185 and #1057586 in llvm-toolchain-16
#1036596 and #1068840 in llvm-toolchain-14

Seeing that some of the bugs are unaddressed for a long time, that many
versions of llvm-toolchain in the archive seem to be to much to handle
for the maintainers. As there is also no progress in removing old
versions from the archive, I propose to not let any new versions of
llvm-toolchain-X migrate to trixie until the number of versions is
reduced to a maintainable number.

Please do not downgrade or close this bug report before contacting the
release team.

Cheers
