Even stronger than that.  There is no reason to suppose
that everyone wants to yank the text only in contexts
where it should be double-quoted.

On the contrary.  People have been usefully yanking it
and using it without quotes for decades.  This is a useful,
longstanding Emacs feature.

If someone wants a different copy or paste or both behavior
then s?he can define a new command and bind a key to it.

If someone thinks that Emacs itself needs such a command
and key then s?he can propose it.  But there is zero reason
to co-opt this fine feature by replacing it by something else.
