Yes, so the systembuilder can install additional groups of applications in

XDG_DATA_DIRS controls which parts of the system are being taken into account
at runtime. It can depend from user to user. It was never intended to be used
at installation time. If it was, a separate env. var. like XDG_DATA_HOME
would have been used.

I'm not aware of any distribution not including /usr/share as well.

Yes, that is the intention and has been the intention all along. For example,
the desktop base directory specification has been saying from the start that
the default value for datadir during installation is /usr/share.
