As this article suggests, it's more likely that they'll push for the use of "traditional ____ units", which will be completely arbitrary, especially since most of the people who knew what these units were are long dead. Converting between them will be a nightmare, and if people start demandimg that, say, all buildings for African-Americans be measured in units used by the Zulu tribes, it'll cause even more divides between white workers ("Why can't we just use feet?") and black workers ("This measurement is my heritage, why don't you want to use it?") This will, of course, be attributed to racism, because scapegoats are useful for such things.
