It wouldn't be particularly "dangerous" if we assume that no one else is
accessing the regression database. What it *would* be is less useful at
catching problems. Standalone mode wouldn't test the cross-backend
interlocking code at all.
Admittedly, running a bunch of tests serially isn't a strong stress test
of cross-backend behavior, but it's not as content-free a check as you
might think. On my machine, at least, the old backend is still around
doing shutdown for the first half-second or so while the next one is
running.
What I'd really like to see is some deliberate parallelism in some of
the regress tests...
