I'm not sure I like this idea.  It means that GnuCash has to be
built against all the various particular DB providers, rather than
just the gda library itself.  I.e. it pulls in ALL the GDA build
dependencies, which (IIRC) was a lot of stuff.

It also means we'd need to do a lot of work to make sure our version
is co-inhabitable with the standard version.

Moreover, it means we have to maintain it ourselves, which is even
more work for us!

It's one thing to include a dependency because it's too new and
most distributions haven't started to carry it (e.g. goffice).
It's quite another thing to include a dependency because the
dependency is too much of a moving target and can't figure out what
the heck they want to support, and wont support existing stuff.

Frankly, I really support dropping GDA and moving to DBI.  Yes, I
know it would require more work, but honestly I think you could
re-use a LOT of the work you've already done.

But I'll repeat, I'm not doing the work so I can only make suggestions.
However it really looks like GDA is going to be a support nightmare.
