It depends on the quality of the surface support you have, and whether that surface support would be able to assist you.
There's not much danger is a pool, but then, swimmers manage to drown in shallow water/pools regularly enough, and they are not encumbered by negatively buoyant scuba kit.
Inflating your BCD and/or dropping weights is the solution to any problem you might encounter, but if it was that simple, then the scuba fatality rate would be much lower than it actually is. The danger arises if you become incapacitated for any reason and couldn't achieve postive buoyancy on the surface. Hence... capable surface support is a good risk prevention measure.
