I can only say that over time, I've had people tell me that when they
enable some xyz-mode, the shift-region keys no longer works as expected.
The cause has always been that the mode rebound e.g. the arrow keys to
some variation of the normal cursor movement.
Adding the 'CUA property to the relevant commands fixed the problems.

However, your proposal to bind S-<whatever> to a command which runs 
the command of the underlying unshifted key would actually do better
than that, as it doesn't need to know in advance what that command is.

Actually, I think your approach is the best proposal so far!

Yes.

I suppose so.

Explicitly binding shift keys -- but they bind them to individual commands.
