<li>Feature variations aren't the only source of non-continuous
changes, there's also the various things one can do with
"location-adjacent" masters, such as sudden kerning changes. And
while most people associate master tricks with kerning and
feature variations with glyph substitution, either mechanism can
be used in either context, depending on what you're trying to
do.</li>
<li>It's not safe to assume that the font's default location will
have all of the right choices. The default weight might have a
dollar sign with two slashes and there might just be no way to
make that work at all other locations. The choices made for
"anim" will sometimes be based on a compromise for what can work
"everywhere". <br>

I started to think about what the wording should be: the advice
would be that you should replace any glyphs which have such
"breaks" by glyphs with glyphs which don't - i.e. replace glyphs
which have Feature Variations by those which don't.
<br>
<br>
Then I realised that instead of having a feature tag, the
animation software could just not bother to process Feature
Variations, or at least have an option to turn Feature Variation
processing off.
