I would prefer 'em from :root'.

em from body, em from #main, em from .refclass, etc were nice also.
And of course 'ex from ...'.

   Because in CSS space separated, multiple values are existing.
   'from' needs to be a reserved keyword too prevent parsing complexity.
   An for complex selector support, if desirable, braces are needed.

So i am strictly against 're' (rem or rex?)!

And btw. '% from ...',
e.g. '% from :viewport' instead of vh,vw (by context).
More stuff '%-height', '%-height from ...',
'%-width', '%-width from ...'.

In this case '%-' before a unit is only a fixed divisor of value 100.
With is easy to remember, and can also be orthogonalized
(%-turn, %-em, but the better mnemonicability is more important).

   Maybe %-fr, with the special meaning of % of the rest (all %-fr).

And instead of 'ch', 'width of "0"'.
(So as special case, you can write 'width of "m" from :root' ;-)

Sorry for my bad English.
