Pacman -Rs instead pacman -R by default

Question

What if pacman uses pacman -Rs by default instead of pacman -R?
When you install a program you want, you install all the necessary dependencies to make the program you want works with just a:
# pacman -S "program"
When you uninstall it you should also get rid of those dependencies without noticing because you never wanted to have them but just the program you wanted to install works, something like:
# pacman -R "program" (and it should work like the actual pacman -Rs "program")
I think is much more common to erase a program with all its dependencies than erase just the program and leave its dependencies installed in you computer, so to erase a program leaving its dependencies should be done by an extra option of R, like:
# pacman -Rk "program" (from keep dependencies) for example and it will do the actual pacman -R "program"
Also its more symetrical:
# pacman -S "program" installs everything to have "program" working
# pacman -R "program" erases everything that was installed to have "program" working
An extra idea is that newbies would ask less how to keep their system clean.
What do you think people?

Answer 1

I sincerely don't like this idea. E.g., I use several packages which were installed as dependencies - I don't want pacman to try and remove them by default every time I remove something that needs them.
Ok, but you could always keep them with another option, like pacman -Rk "program" as I gave as example. I understand that you might need them but which action is more commonly used, even for you: uninstall just the program and keep dependencies because you are going to need them or uninstall the program and dependencies?
The current solution is a lot more K.I.S.S. (i.e., the action taken with the least options is the most basic one - this is intuitive to me).
Ok, intuitive for me is to keep my system as it was before I install anything with the least options.
Not intuitive, for me, is to do pacman -Rs anytime I unistall something, why? because I did just a pacman -S to install it
Moreover: I am always against changing something that works well.
Yes, it works well but you can always do things even better, easier, faster, whatever.
And you can make aliases to emulate this behavior if you wish.
No I can't, I don't know how to code yet. And I think this idea is good enough not only for me but could be helpful to the arch community.
