I don't use latin-postfix, because it gets in the way: there are many
more combinations than in italian postifix which change what I am
writing - this is an added burden for a minuscul added benefit.

This is why italian-postifix exists, in spite of the existence of
latin-postfix.

I don't use C-x 8 either, because I'd have to learn a lot of complex
bindings: when I need some exotic char I use the terminal or the X
combinations, which are easier and not specific to Emacs, unless I am
forced to.

This has little to do with italian-postfix, in fact.

All in all, I don't get your objection.  What would be the drawback of
adding the E = keybinding?
