[MariaDB developers] Question about lacking git commit message in dc9498b

Hi Sergei and others! While reviewing changes in MariaDB 10.11.5 I was wondering about this commit: https://github.com/mariadb/server/commit/dc9498beb6f79f08edd02fb7f7153e5150a... It has only the default message from issuing 'git revert' and a human written explanation *why* the revert was done is missing. AFAIK the reverted commit https://github.com/MariaDB/server/commit/1d0e3d80d84c2b375a444cdbb41c28afd78... was correct and good - so why was it reverted?
