Hi,

With the latest oslo.db 12.1.0 release it seems multiple repositories are broken (see the corresponding requirements patch [1] for details, and probably there are more, that are not tested within requirements repository). The patch that introduces the break [2] "is necessary for oslo.db and openstack applications in general to be able to run on SQLAlchemy 2.0" according to patch author.

Since we are after the 3rd milestone of Zed, we have very limited time to figure out what to do. The 2 options are:

1) fix every broken repository to work with oslo.db 12.1.0
    as far as we know this is quite impossible as for some repositories the already existing fixes took almost a cycle to be implemented and there are still undiscovered bugs around this. (we don't know if this is really true, or probably there are cases where it's easy to fix)

2) revert the breaking change [2] and do another release in oslo.db now without it (and add it back after Zed release & release oslo.db with it as soon as possible in Antelope cycle)
    as far as we understand this does not cause any issue for those who already adapted to oslo.db 12.1.0, so this should not be painful

Based on the above Release team is opting toward the 2nd option.

Please let us know your opinion!
