Profile is term used in ISO, I don't know whether W3C slang uses it as
well or have something similar. Although not saying it explicitly
Polyglot spec in fact defines what would be called HTML5 profile in ISO,
or subset between mortal people.

Working Group, or even wider Web community -- I don't expect that anyone
sensible would promote UTF-16 as a recommended encoding.

If anyone wants to do this detective excercise to figure out whether
some restriction comes from HTML5 spec, XML spec, legacy browsers
behaviour, ... then he is certainly free to do it and it would be
interesting to have this in the spec. But I doubt that average reader of
polyglot spec would be interested in this -- he/she needs to know rules
to follow and that's it.
