I'm trying to think of any other areas that could be improved. What do people think about a cutaway heel? Here's Fender's own version on an American Elite Strat.

Would something like that be worth it, or do people feel it would be too small a change to make any real difference to upper fret access?

There is of course nothing stopping anyone from doing this themselves and buying a 3rd party neck plate, as long as the neck came undrilled, otherwise the original neck-end high E side screw hole would be visible.

Any takers for this as standard, or leave as a DIY option (as long as an undrilled neck was available)?
