They do. XeTeX provides \XeTeXinputencoding (specific to the current file) or
\XeTeXdefaultencoding (all future files input'ed). LuaTeX provides all the
necessary callbacks, luainputenc provides a LaTeX interface to them, and can be
expanded if necessary to cover more use cases.

That's why the encoding declaration should be done on a file per file basis.
\XeTeXinputencoding is the perfect solution for people wanting to declare their
file's encoding, without any interference with the outside world, and can be
easily enough emulated in LuaTeX.
IMO, the engines already provide the tools needed, now it's up to macros writers
(and perhaps format maintainers, but that is another story, to be discussed
elsewhere and probably later) to use them.
