protrusion and expansion are supported at the luatex engine level but
configuration is up to the macro packages and they can follow different
approaches
the other things ... well, they are up to the macro package

yes, context supports that (more than just letters)

what title page? anyway, one can kick in extra font features to deal
with kerns (although when a font is that bad i'd use another font)

probably because it is so standard

pdftex is an engine so even if something is available it has to be
supported by macros
i don't think that there are typographical advantages of using pdftex
over luatex (at least not with context)
