@aschmitz@Lady Yeah, I'd be more worried about things like security issues and general maintenance in the style of cleaning small bugs and obsolete workarounds, than keeping things building.
Distros can help a bit on security issues but packagers jumping in codebases they aren't much familiar with doesn't always works so well.
@lanodan@Lady Kind of, yes. Though systemd and ninja only need it for building, nginx only(?) needs it for libnginx-mod-http-xslt-filter, and php uses it for php-xml. And we're both leaving out things, but I was just sort of surprised by how few things actually seem to have firm dependencies on it. On the other hand, there's enough that if it stopped working with, say, a new glibc/musl version, there would probably be a fix in short order.
