Hi,

One concern on this matter is how it affects to the visibility when
mixing up the fonts with/without ClearType bytecode. I may be wrong
because I''m not checking that myself. but just heard one get tired
easily to keep looking in that situation. dunno.

Other than that, it may be useful for buggy fonts.

As Windows still has an option to turn off (right?), it just sounds
not so bad idea to me. having said that the flag might be deprecated
in the future though.
