The NE region list is available, if you want to start. You don't need to wait for a MapRaid to start it.
For various reasons, I would advise "not yet." But indeed, there are some names that have been mostly standardized... Though for some businesses, the details might be subject to change (e.g., do we include "DD" as an alt for Dunkin' Donuts? What is the primary category? Coffee shop or fast food?)
