Because 4GB should be enough for anybody?

Seriously, it is trivial to define block lengths that can be 1, 2, 4,
8 bytes long.

0-0xFE - 1-byte length
0xFF 0-0xFFFE - escape + 2-byte length
0xFF 0xFF 0xFF 0-0xFFFFFFFE - escape + 4-byte length
etc.

Just because some theoretical developer might get this wrong is not an
argument for making a more complex (fragile) design which allows user
data to imitate framing data.
