except for the fact you can't use backticks in posts anymore. they
will be replaced into oblivion.

don't worry. new major versions of MySQL tend to be so unstable, they
have very slow adoption.

furthermore, this whole backtick argument is just smoke & mirrors:
 - all SQL in WP is backtick-free except for update.php
 - will a patch to add backticks to all other SQL be accepted?
 - if indeed it was good practice, the "good practice" would be ...
well practiced. it's strange i haven't seen it practiced in other

you might as well write
  (x + (2*y)) instead of x+2*y

because... well... you know... perhaps the precedence of * over +
might change. better be safe than sorry! you never know!
