Agreed.

I would personally say no. The driving reason for Adam was to be able
to build the SELinux stuff. But indeed, if you're adding all the
SELinux overhead on your system, you most likely have the filesystem
space needed to switch to glibc.

So I'm fine if we decide to say "no". It should hopefully increase the
pressure on the upstream projects to move away from a legacy BSD
interface, and use the POSIX interface instead.

Best regards,

Thomas
