According to http://www.tldp.org/LDP/abs/html/bashver4.html#AEN21183,
bash 4.1 was released on May, 2010. Are you sure macOS is _that_ late?
I also tried with dash, and -x seems to work fine too (I use "works with
dash" as a heuristic for "should word on any shell", but it doesn't
always work).
If -x doesn't work in some setups, it may be a good reason to wait a bit
before trashing test_path_is_*, but if it's clear enough that the vast
majority of platforms get -x, then why not trash these wrappers indeed.
