Bad excuse, we ship a lot of services default-disabled, we could ship
default-disabled srv layouts

We can provide examples and templates. Users that know better will do
what they want as usual. No best policy is no excuse for no policy. Half
our stuff in /etc could be configured some other just as good way we
still make a choice.
A distro rpm layout is a layout that just works with distro defaults,
which is already quite a high standard.

You can provide a default webdav/ftp/samba layout, we've done so in conf
files for years.

Again you're making it a special case when the same arguments could be
used to advocate no choices in most of the filesystem. We're not gentoo
we make choices for users and then let them amend our choices.

No, /var/lib/foo is mixing local apps and content, that's the kind of
mixup that got stuff kicked from /home in the first place.

They should. They will someday. Or something else will deprecate /srv.

That only means you have several resources, and you can map them to
several domains, not that the resources names should be domain names.
