If it's straightforward it doesn't bother me.  I'd have to see the code
involved.  It seems likely that it would be sufficient to require
copyright assignment.

As mentioned by Daniel I'm uneasy about, basically, inventing a
completely new, fully functional language in make.  We already have
plenty of those.

I suspect it's not what Tim has in mind :) but for what it's worth, GNU
make has supported using Guile as an extension language since GNU make
4.0 (2013).  Making simple enhancements and performance improvements to
make's language is fine but if people REALLY need a full language I
think an extension for an existing language is a better bet.
