But the context of "main" *is* the whole page, so there is no additional
context available to determine which one it would be.

I think what you suggest is that it would be the first, or would it be the
deepest, or the one in between <header> and <footer>, or .... you see? You
require a complex algorithm to determine which it is, that is the whole
point of what <main> is for - so that a complex algorithm is not necessary
because there is "only one".

If you can come up with a guaranteed algorithm i think we remove the need
for "main" (or even ARIA) altogether, in the absence of that accessibility
users need the explicit assistance.
