For more than 3 year I've not seen "magic_quotes" or "globals_on" turned on anywhere. As far as I know in php6 there won't be globals option at all.

Neither have I. If you care one bit about security, that's the first thing you'll find out about PHP and as you said, they are being eliminated from the php.ini file in php6 and will need to explicitely turned on in your scripts.
