pkg_rolling-replace is written in sh.  It's not super hairy, but it's
not trivial.  It is possible that not likely it will trigger a bug in
sh, but it seems far more likely other usage will find the bug

It's also possible, were there a bug in sh, that any particular package
build will fail.

So certainly, it makes sense for people to try things in various ways
and track down issues.
