@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.
