This seems more like an additional burden for frontends which cannot
rely on a specific gdb version being installed as they have to keep
code to parse both results, for years.

The fact that the current output might not conform to the documented
grammar has no impact to existing frontends as they have/had to cope
with this kind of slight deviations anyway.

An alternative approach would be to just make the documentation match
the actual output. This is not unprecedented.
