I am not very familiar with this topic, but need to maintain large and frequently updated DB, which requires periodic VACUUM FULL with full tables lock, so, does PG suffers from index bloat only and your fix solves it, or there is some other type of bloat for general table data too, which will still exists after your improvement?

It's not possible to give you a simple answer, especially not without a lot more information. Perhaps you can test your workload with postgres 14 beta 1, and report any issues that you encounter to one of the community mailing lists.
