Ill drop my own quick thoughts into this, that we could just treat these as we'd do with any other new subrace? For example, with the Astral Elf, it was classified as its own race rather than a subrace, however we listed it in the Elf page in full since well, its an elf. For about 95% of the races here, thats the easiest thing to do for the frontpage. The only ones that would need a bit more thought would be the Changeling and Satyr, though the easiest option for that would be to list them twice? Once in setting specific, and once again in exotic? and then have the exotic one have a '(MoTM)' next to it, and then the link leads to the changeling page auto scrolled to the MoTM version
Its no where near as clever or well thought out as the lineages pages and other ideas we could go down, but its definitely the most quick fix we have for it
Though yeah, we might just need to rework the whole race section of the frontpage at some point.
My thought on a rework is that maybe we set it up like we did the Heroic Chronicle, with the big text, text beneath it, and then links? And then from the links, we probably have 1 general link for all races, and then maybe smaller focused links for say, Unearthed Arcana ones, and Setting Specific
Also, yeah most of the races will probably need to be listed seperately, since a majority of them are different to their previous printings
