I don't think this would necessarily be a good thing. The advantage of
glyphnames.json is that it provides a simple, effectively flat list of the
glyphs encoded in SMuFL. We could potentially add the range as a key/value
pair within each glyph, so the structure would look something like this:

{
    ...
    "4stringTabClef": {
        "codepoint": "U+E06D",
        "description": "4-string tab clef",
        "range": "clefs"
    },
    "6stringTabClef": {
        "codepoint": "U+E06C",
        "description": "6-string tab clef",
        "range": "clefs"
    },
    ...
}

but the disadvantage here is that you would have to assemble the list of
ranges yourself, and there's no elegant way to define the human-readable
names of the ranges, or the code points they encompass, within this
structure.

It's not difficult for us to produce multiple JSON files and it strikes me
that each file might be useful in different circumstances.

Similarly, with classes we could encode the classes for a glyph as an
array within each glyph's entry in the glyphnames.json file, like this:

{
    ...
    "4stringTabClef": {
        "codepoint": "U+E06D",
        "description": "4-string tab clef",
        "range": "clefs",
        "classes": [
            "clefs",
            "combiningStaffPositions"
        ]
    },
    "6stringTabClef": {
        "codepoint": "U+E06C",
        "description": "6-string tab clef",
        "range": "clefs"
        "classes": [
            "clefs",
            "combiningStaffPositions"
        ]
    },
    ...
}

but again you don't then have a classes-first representation, and you have
to enumerate the classes yourself.

So my inclination would be to keep these files separate, but I would be
interested to hear the perspectives of other folks in the community.
