Right. In fact some current distro providers do
install LSB support by default and some don't, but
in either case selections at install time could
alter that situation.

That's the way it's set up to work. Right at the moment
there's just a single package manager dependency called
"lsb" that, if met, indicates all the necessary packages
are in place on the system. Typically, that dependency
is provided by a distro "virtual" package that simply
depends on everything required for LSB support.
