if you also introduce BIT_AND and BIT_OR as internal (not UDF)
functions then it's OK. [system?] views could be defined to turn the
bitmasks into something more readable if and when the need arises.

If BIT_AND and BIT_OR are not available, on the other hand, it's
gonna make the life of catalog-exploring tools like FlameRobin
tougher.
