I'd suggest putting a comment in the code to that effect.  With the way
"cleanups" get done, I wouldn't be surprised if this attracts a lot of
people wanting to do a trivial "1 << bit" -> "BIT(bit)" conversions.

One of the problems of open source is that you can say "no" to a patch
like that until you're blue in the face, but it will eventually make
its way in via some path.

Just one of the reasons I consider BIT() to be evil and an inappropriate
macro.
