I would think that making it manage musl/alpine first-class and not require a branch in the road to deal with it, was worth the effort. Things like this make it harder enough that people will do hacky modes of work to get around it.

(I hit similar things with libressl/libcrypt from time-to-time. It is not quite exactly a drop-in replacement world for these things. It's painful enough to make back-porting modern SSL dependent code a royal pain, of destroyed shared lib dependencies)
