Certainly tagging foo=yes to indicate that amenity=foo exists as part of
another feature is standard practice in many cases (atm, toilets, bar
being the most prominent).

Nonetheless I think bbq=yes is ambiguous. To me, the most natural
interpretation of bbq=* is to indicate whether barbecuing is permitted,
rather than to specify the presence or absence of an on-site bbq apparatus.

Consider the situation brought up in this thread last month:

https://lists.openstreetmap.org/pipermail/tagging/2019-June/046064.html

The question was: how to tag a feature where barbecuing is permitted,
but no fixed bbq grill exists? The best suggestion was
bring_own_bbq=yes. But the combination of bbq=no and bring_own_bbq=yes
seems contradictory. Despite the inconsistent spelling,
barbecue_grill=no + bring_own_bbq=yes makes more sense... slightly more.

I'm afraid the possibilities are complex enough that I'd actually
suggest using a bbq:* namespace, ie:

bbq=yes
bbq:grills=yes/no/1+
bbq:bring_own=yes/no

There's the issue of redefining bbq=yes, which has 219 uses... but those
219 uses are already ambiguous IMO -- the only thing I know for sure is
that barbecuing is permitted there. So I don't actually think this is a
redefinition, just a clarification.

(These subtags could also be used to clarify amenity=bbq, which
according to Joseph Eisenberg at
https://lists.openstreetmap.org/pipermail/tagging/2019-June/046072.html
is already ambiguous on the German version of the wiki, covering both
the grill itself and the area where grilling is allowed.)
