Just on a general note:

I would like it if toolchain version bumps were discussed somewhere else first, 
not in a PR. (And apologies if it was and I missed that discussion). Because 
PRs are usually followed only by active developers, but toolchain versions 
affect a broader part of the community. As we have seen in this PR, there are 
conflicting interests.

We have things like CSRs and JEPs. Both are not ideal - a JEP is way too 
massive, and a CSR is about the compatibility of the product, not about 
build-time. Still, maybe something like a CSR would make sense here.

I understand that with toolchain support, there will always be opposing 
parties, and I can see arguments on both sides. We don't want to end up like 
FreeBSD - stuck in time because of opinion stalemates. I just keep thinking 
that a PR is maybe not the perfect forum for this.
