My feeling was only subjective based on running from "emacs -Q", but
that may be problems with font lookup making everything slow.
I've now bootstrapped the master branch after you merged the harfbuzz
support, and everything appears to be working fine so far.

Agreed, but it would be nicer for the average Windows user if the
built-in fonts were used by default, and that configuring the fontset
would only be needed to override the default selection.

That's reasonable when recommending additional fonts to install, but it
is unhelpful to avoid using fonts that are installed by default.
