I don't see any reason to forbid it either. Let's see
COMMENT ON DATABASE IS <value | null>
merely affects the single record in rdb$database. But we can reuse reserved
words to make clearer the purpose of the command as opposed to affecting a
single object. Looking at our existing tokens, I can produce a wild syntax:

COMMENT OVER ALL DATABASE IS <value | null>
or simply leave the oly option to be
COMMENT OVER ALL DATABASE IS NULL
because I think the typical option is to clear comments, not to put
something silly instead.

The problem is that we lack equivalent commands for sources and debugging.
Then if we want uniformity, what about

ALTER DATABASE DROP COMMENTS
ALTER DATABASE DROP SOURCES
ALTER DATABASE DROP DEBUGINFO

Replace DROP by CLEAR if you like.

ALTER DATABASE STOP DEBUGINFO -> do not log debug information anymore.
