I don't think the main issues are with file _formats_ but rather with
system file structures - AFAIK it is a fundamental design decision
(arguably a design flaw ;( ) that we use system tables straight from
page cache via C structure pointers, even though there seems to be a
layer called "storage Manager" which should hide the on-disk format
completely.

I don't think that is a big issue, no one is saying the file format should "change" or be used any differently, just that the structures be more rigid, and anyone wishing to make a change, had better also have an upgrade strategy.

Perhaps there could be a review/document phase for 7.4 where the structures are cleaned up, checked, and perhaps have a couple "reserved" entries added. (As governed by efficiecy) and have one last "speak now, or forever hold your peace" and cast them in stone.

I think, as professional standards go, this is probably LONG over due.
