So generate them mechanically; I have a program "renumber" that's
specifically designed for producing the numbers for lists of #defines
like these, and it has a mode where it generates walking bits instead
of consecutive small integers.

And they have plenty of problems of their own, most notably that they
make it impossible to manipulate more than one bit (or field, if you
use multi-bit fields) at a time.
