These all sound reasonable, but experience shows that nothing will
establish their usefulness except widespread testing over lots of different
kinds of loads.  For example, if one consistently uses a numeric character
reference, it may well be compressed just as tightly as the corresponding
UTF-8 character or conceivably better.

So if you believe this, implement, release your implementation as Open Source,
and let the games begin.
