On well-made lutes - bridges don't sink.

Unfortunately things don't work that way. Generally over time the tension of
the strings pulls the bridge towards the neck so that its front edge sinks and
this is what causes the bulge in the soundboard you refer to. It's true that if
you have no dishing, this immediately makes the lute virtually unplayable
(which is another reason I like 6 mm or so of dishing). I don't think there is
any evidence (or physical explanation I can think of) to suggest that a flat
soundboard is going to be more subject to this phenomenon than one with
dishing, it's just that the latter has more leeway. Different soundboards seem
to react in different ways. I have a lute which is over 20 years old which has
virtually no sign of the bridge sinking whereas a more recent lute might show
signs of a sinking bridge within a very short period of time. I suspect that
very thin soundboards are more prone to the problem.
Some late baroque lutes had convex bars between the rose and the bridge which
might have been intended to try to limit the phenomenon of the bridge sinking
over time. The corresponding bridges would have been convex.

Physics, I suppose!))
The pull of the strings deepens the scoop, rather then lifting the bridge.
The non-concave soundboard also carries a large risk of becoming convex, and
I’ve seen a few lutes with a nasty bulge between the bridge and the rose.

The scoop keeps the action stable, and that’s its main function.
An axe without the scoop is a disaster to be avoided.
