If it were doable, I would perhaps agree, but I hardly see a way. (Except
creating a "bytes mode" in XeTeX/LuaTeX and making it the default, which would
IMO be a greater evil that the small problems we're facing now.)

Already with current latex/pdftex, they can't without restrictions. The
restrictions will only be slightly higher with LuaTeX/XeTeX.

(If "we" is understood as "TL/ctan2tds", then I agree that we should be liberal
and treat everything as bytes in an encoding-agnostic way and without altering it.)

I don't see asking people to declare the encoding they use (or at least whether
bytes mode or some-variant-of-unicode mode is to be used) as an unacceptable
pressure on authors.

Line endings are technically easier :-)
