Uber really just needed a key/value store. MySQL works better when used that way since PostgreSQL has MVCC and can lead to table bloat and compaction issues.

I doubt many others ever encounter this issue since picking the correct data store is step 1.

InnoDB also has MVCC. Always has. It just uses a different strategy to avoid the table bloat and compaction issues.
