I hear that.  Let's try to think about smarter ways for the code to behave.

I'd rather not.  Doing the right thing is better than options, when
you can figure out what it is.  And too often, adding options becomes
an excuse not to figure that out.

How about this: VC can test whether some VCS considers itself responsible
for a directory.  I could change the logic to error out when no VCS considers
itself responsible for the current directory. Would that cover your
use case?
