Doesn't matter, it's the size of the event horizon that counts, not
the singularity. As long as there is enough mass inside an event horizon
there is a black hole, even if there is weird physics unknown to us
inside that prevents formation of a singularity.  We can never know what
happens inside an event horizon.

We see that Sgr A* is there, not by seeing it, but by tracking stars
that are orbiting it.
