(The former is correct, but the latter should say libgl1, not libgl)
I don't think this is a bug. libgl1-mesa-glx was an implementation of
the abstract libgl interface. Xorg now depends on libgl1, which is a
vendor-neutral dispatcher that loads one of several backends, including
Mesa's: because it's vendor-neutral, there is no longer any need for
alternatives.
libgl1-mesa-glx is now a transitional package which pulls in libgl1
and libglx-mesa0, and (indirectly) libgl1-mesa-dri, so adding it as
an alternative would not help to make libgl1-mesa-dri more optional.

libgl1-mesa-glx | libgl dependencies being replaced by libgl1 is part
of the GLVND transition, but would not necessarily cause the symptom of
a transitive dependency on libgl1-mesa-dri.
I think that might actually be caused by:
mesa (17.2.0~rc6-1) experimental; urgency=medium
...
* control: Bump libgl1-mesa-dri to libglx-mesa0 Depends, it's needed
for swrast used on some tests.
If I'm correct about that, then this bug should perhaps be reassigned to
libglx-mesa0.
Perhaps it should be those tests that explicitly pull in libgl1-mesa-dri?
(Although I do question how useful libglx-mesa0 can possibly be without
the DRI drivers that make it work.)
