No plans that I am aware of, but I am in favor of being bash-free.
Thanks!

That would be great!  Do you plan to work on this?  While not required,
if you open a github issue for it and tag it with a release, we can 
note that this work occurred in the release notes.

You might also consider adding something to the docs/anti-patterns.md
for this to really solidify that we want to be POSIX compliant in
meta-phosphor.

Thanks!
