We discussed this in a thread on bug-bash back in April:

http://lists.gnu.org/archive/html/bug-bash/2015-04/msg00183.html

This discussion references an earlier bug report concerning whether the
--debugger option should produce an error if the bashdb script is not
installed.  There is also an issue with bashdb misbehaving when run in
an interactive shell; that was the reason for the check of $1 in the
first place.

Part of that thread explains why a check of $0 is not correct: since $0
is always set, a check for it has no effect.

The final change that solves both problems went into the bash development
branch in early May, and will be in bash-4.4.
