Exactly.

I won't put quite as much energy into debating that, as we are now much closer to agreement than before. :) 

I do still prefer one keyword rather than 3-5. Or even three and always three ('bottom-left to top-right' and 'left to right'). One keyword works best for me, because there are only eight variations and direction is then as simple as "pick an angle or a keyword", and the canonical way is the commonest English-language way, with no confusing this with actual bg-position syntax. Border-radius has that sort of thing as part of its longhand property names for describing the same sort of corners on element boxes ('border-radius-top-left', for example). Before I had 'border-radius' syntax memorized (and when I was used to FF doing it differently that Safari), the hardest part to remembering if the corner name came before or after the "radius" part of the property name. I never had any problem remembering the order of "top-right" and "bottom-right", etc. Because that is the way people say them naturally (unlike with 'background-position', where I STILL have problems remembering the proper order rules, which you saw in my earlier email).

Probably even more than that. My 'as-square' keyword was meant to pick up most of the remainder (for other angles that could stretch with the box), but yeah. This could be good enough and keep the simplicity.

Exactly. We can wait and see if we could pick up another 5% or so with a 'as-square' or 'stretchy' or whatever keyword, and if that's important enough for the extra "indirection".
