I want to start by saying that gripes/land mines don't help anyone. We try to balance fixing these issues, while keeping a good upgrade story. XKCD does a good job of explaining the problem in https://xkcd.com/1172/ https://xkcd.com/1172/ In every major release we have a pseudo quota for incompatibility (5.5 changed default storage engine, 5.6 and 5.7 refactored a lot of the optimizer and transitioned defaults like strict mode on, 8.0 makes large changes to data dictionary). w.r.t Ikea of databases - I have a large Ikea desk that I sit some very heavy computers on. It is simple in design, but that does not make it limited.
