The big issue is an edition designed to be for everyone should have variant rules for everyone. To me the biggest mistep in 5e is not be released with a ton of optional variants at the start of it were going to be for everyone but have a traditional Old School base system assumption.
How much a +1 STR is worth for a fighter should be up to a table and decided by which variants the table uses. 5e missed the boat on that one and has been playing catch up ever since.
