IOhannes is correct in that "-lib" behavior hasn't changed (I just
tested with 0.45). Considering this, it's probably wise not to change it
now, although I feel more sympathy with the use case you described. I
don't see anything wrong with having to use [declare -stdlib zexy -lib
zexy] in case I want to cover both, relative to calling patch and all
standard paths.
