Hello,

the two modes was something that I didn't like, at all, as a userland
developer. It seems really scary that decision to add 2 modes would
mean that every PHP code could have been written in any of these 2
ways and it would stick forever with PHP, because removing it again if
it proved to be a bad feature would be IMHO really painful.

So a single mode is infinitely better than 2 modes.

Also, personally, I would prefer #1 or #2 version for internal
functions, but definitely without an INI switch. Not being able to
change it on some hostings could make development for the transition
period kinda painful.
