yes, it allows people/layer maintainers to decide which version they
want easily

this is fine as there is stable 4.7.4 and some people already started to
use 4.8.0 by their choice (which is easier to do with P_V then
adding/removing some fancy qt-4.8 layer).

if someone really wants to use development version of it, why force him
to use different layer? and -2 is because other mesa-dri versions have
-1 from .inc.

this is because there are other virtual/libgl providers and this was
used to demote mesa-dri as provider for it

Because people need to think before switching from 1.6 to 1.7 because of
tarballs of svn checkouts are not compatible.

explained in previous thread.

Because there were recipes for released versions and there will be
again, so it makes sense to use releases by default if they are not
lacking behind much - like they do now.
