So you are the only one I know so far with that opinion.

This is the same problem than undo-redo. Maybe the features are actually better
technically speaking or to whom knows all the tricks and trains himself for
years; but it worth nothing if the users feel uncomfortable or don't values
some of the details that justify complexity in others. (Like hiding the context
panel with a control or not having a redo button or not deleting the selection)
Or just don't need them.
There are some "standards" in mouse interaction determined/imposed by most of
the gui programing interfaces from visual studio or java to qt5 and gtk. The
developers of all the aplications have been following them for years and most
of the user are used to them.
So this is the "dilema". Or we change a bit (1 binding) to ease the user
experience and learning curve OR we expect that all the potential users change
their expectations, trainings and don't go to any other editor but use emacs
because we pretend we offer a better functionality that they are not aware of
and most probably don't need or never learn/use because is complex to remember.

Usually the other hand is already in the keyboard and close to a shift.
Comparing, our approach of moving the mouse to the toolbar to copy after the
selection is probably less efficient than anything else or the fact that M-w
and C-y dont share any key like C-c/C-v or that we need the two hand to undo
instead of C-z. All these are less efficient too but we are used to them.
So the argument of holding a shift seems a bit weak for any old emacs user
>(One of the arguments made by a few people in

No, the argument is also that many applications intercept that C-mouse action,
in terminal doesn't work AND the user don't expect it to be there because
probably we are one of the few (or the only) hiding the panel there after a

But just the same button-1 so yes, probably simpler to remember and intuitive
for any office (or other modern editor) user.

And again, they are the same, mouse-1 and shift, so exactly the sames... This
is a pattern. Select with mouse-1 actions in panel in mouse-3 move with the
Simple is better than complex.
Complex is better than complicated.
The emacs approach with mouse is indeed complicated.
