Few Windows users use those commands.  The ones who do are generally 
exactly the ones who know how to edit the PATH variable themselves.

For most users (the ones who start R from the shortcut), there's no need 
to mess with the PATH variable.  Personally, I hate programs that do 
that.  And with R, it's now complicated, because there are 2 different 
directories holding executables:  bin/i386 and bin/x64.  (The bin 
directory also holds some, but that's just for back  compatibility.)
How could the installer know which of those to put in the PATH?  At 
installation time, a user isn't going to know which one he/she needs.

Multiple installs give you the possibility of reproducing things that 
don't work in the latest R version.  I think it's a good practice to 
keep multiple installs on your system if you have the space, and since 
disk space is cheap these days, that's not so uncommon.
