It seems like y'all are unearthing every single crazy command line
option choice out there. Great to have this fleshed out.

This makes good sense to me. It hides the actual nastiness a bit and
makes it clear in the code what is happening -- assigning multiple
parameters to a single option. It sounds like a great way to handle
