BDB 5 is unmaintained. There's no one upstream working on it, since
Oracle has moved onto BDB 6. No one wants to use BDB 6. RPM should not
depend on dead software. And there are significant performance
advantages to LMDB, according to various benchmarks[1]. And LMDB looks
like it could enable making the RPMDB to be more resilient[2].
