One outstanding SRFI 170 issue, chown hga@xxxxxx 12 Aug 2020 17:40 UTC

In going back through saved for later SRFI 198 emails, I came across
an outstanding issue for SRFI 170:

>> For making Scheme interface align with chown(2), I'd like to push it

That matches the POSIX API, plus chown(1) has "user[:group]" in it's
official argument list, and I personally use that a lot.  It was also
noted this allows atomic updates of both, although it's not clear
that's really useful in practice.
