We are heavily utilising back-sql on our product. Granted it has its issues but it does so far fulfill our needs. We are currently running on 2.4.58 which we build ourselves for Debian and RHEL/CentOS based systems. We needed couple of patches to back-sql to make it work for us. I just created issues (and added my patches) for them. I don't have a slightest idea if the patches are of any use for you but they make our environments work.

Removing back-sql from future releases would make us stuck with 2.4 release.

Not necessarily, that's why I started the discussion. back-bdb was
deprecated with 2.3, but was around for all of 2.4 as well. I see no
reason to keep back-ndb around. back-sql has numerous open issues, but
I've no real insight into whether it retains any usefulness.
