First problem is to actually detect what key was pressed, in most

Changing terminal emulators to support this and making this work with
Vim is a separate issue, I'll not go into that here.
Changing terminal emulators is a done task; xterm has supported this
since 2008. In fact I asked Thomas Dickey to clarify this for me, and
he informs me it's all present and working.
Despite its popularity, xterm is not "most terminal emulators". I think
this is a great move on xterm's part (having a more-or-less consistent
set of escapes for modifiers). But, it's still a chicken-and-egg
problem. Once it's in xterm, it takes a while (if ever) to filter down
to derivatives. And even under xterm the setting that allows this to
work isn't the default.
I almost didn't send this, since I don't think the lack of terminal
support should be a show stopper (If any terminal supports it, Vim
should use that support), but claiming that it's a done deal because
xterm added a feature to support it a few years ago is naïve.
