Eh? So what is by and large? Does that mean some queries will be less efficient?

For example, how about if my module in contrib perform an ORDER BY on
node_revisions fields such as timestamp and uid? This would require a
filesort on the entire table ... Will these be unaffected?

This is essentially:

a) Taking away choice.
b) Increasing table size.
c) Introducing inefficiency.
d) Loading the table with potentially unnecessary junk whether I like it or not.
e) Asking me to sort any resulting issues out with another contrib module.
f) Telling me what's good for my site.

... all for the sake of a couple of checkboxes.

No thanks. -1.
