Yes, that's the jist of it.  The main advantage is that it has a much
smaller dependency chain locally.

I find it useful on some of the not-particularly-fast ARM systems I've
been running GNU Guix, where storage may be limited or slow, and
substitutes may not be available as often, and build times
are... remarkable.

It is essentially SaaSS.  The server-side is at least licensed under the
AGPL, if that mitigates concerns somewhat.

I'm not sure it supports it out of the box yet, but I suspect upstream
would be amenable to patches to make it easy for people to run their own
"diffoscope" services.

I thought it was useful enough to be worth submitting, though I'd
understand if it's deemed inappropriate for GNU Guix. Still learning the
ropes. :)
