I think this is rules bloat for little gain. Adding them to the book does very little outside providing nebulous "guidance" on how to use a monster. It'd be different if the guidance was broadly useful, but it largely isn't. I don't need a role tag to tell me to put the archer at a distance. I believe most DMs simply would ignore them.
A more useful implementation is the one in amazing Forge of Foes by Sly Flourish. There you have templates, and suggested abilities to add, for each role. This, to me, seems far more useful than a label that tells me something I already know.
If the updated monster manual was to include the Forge of Foes version, I'd be overjoyed. If it was to use the former "tag" version, I'd simply ignore it as it does nothing.
