We have been using the current grid naming model to build real applications quite successfully. As for differences, they would matter for those people who will be able to notice them due to their familiarity with all the w3c technologies where it is deployed. That population may well be too small in practice to cause significant confusion.

I'm not concerned if we decide to use different terminology than XSL:FO,
provided it's better.

My concern is that in 2D contexts (e.g. GCPM 'float' keywords, or 'caption-side'
values or logical margins), authors will have to use the start/end pair in the
main axis and the before/after pair in the secondary axis. For alignment only
to use start/end in both axes will be inconsistent, and therefore confusing.
