(Note: I have no idea what this particular case is about)

PurePerl programs are often useful because they have less risk of
crashing horribly via a segfault. I'm not sure how this applies to
something as well-tested as the Digest::SHA module or the C
implementation of the algorithm.

It should be noted that while all arches can build and run XS modules,
it doesn't preclude a given arch from being unable to build a module
properly. In that case, it's convenient to be able to fall back to a
pure perl equivalent easily.

Neither of these is really convincing (not to me, and probably not to
you), but it's the best I could come up with.
