So it seems there's agreement that we do not need named grids. That's
an important simplification, one that motivated me to write up this
proposal:

Indeed, the "none" value is part of the proposal above. It think it
makes sense to try using one property for most of the baseline needs.

Also, I think the "root" and "page" values are useful. "root" is a
grid defined by the font/position of the root element, while "page" is
a grid defined by the page area + the font of the root element. To
avoid show-through in printed matter, it is important to have a
baseline grid that doesn't change when page margins are change. For
example, the page area on the first page of a chapter may be different
from those on other pages, but we still want baselines to match.
