Probably. Well actually I can think of only one situation where it makes
sense to use the property in the matcher: The user intends to use Unicode
characters (where a limited set of emoji has been standardized as far as I
understand) and wants to give a hint that the result should be optimized
for a monochrome printout.
Although in such a case, they would probably even prefer scalable fonts --
some of them *should* really have Unicode emoji --, in which case the
existing property 'antialias' would do a similar job; at least as long as
there's no support for scalable color fonts.

In the case of non-Unicode symbol fonts, I expect that users will almost
certainly select the fonts by their names and then the property has no
useful meaning for the matcher.

These should be some real corner cases. The danger that a user who wants
the usual b/w rendering is *accidentally* presented with a color glyph
should be near zero as long as fontconfig doesn't use color fonts as
fallback in its default configuration. This leaves the scenario that they
like the shape of certain glyphs in certain color fonts but want to use
them without the color even if they're targetting a computer screen, then
yes, there might be a use case for copying the property into the font. But
we might as well leave it for them to configure...
