I like this proposal for its use of only a single command with the
add/remove/reset in the args. If \feature ends up being too generic,
maybe \fontfeature or \fontfeatureset instead?
To keep things more in-line with current ConTeXt syntax, you could do
something like the following:
\feature{add=foo}
\feature{subtract=bar} (or sub, remove, etc.)
\feature{reset,add=baz}
Which would also allow, e.g.,
\feature{add=bar,remove=baz}
similar to how we're used to using key:value pairs in so many
arguments, and being able to combine them in one function call.
