The idea that a shell should save a copy of every variable's value at
the moment it begins accepting interactive commands, so that you could
switch back to this previous value in case you "accidentally" change it,
is quite bizarre.
The idea that a shell should do that, but only for "special" variables,
is even more bizarre.
If this is important to you personally, then you could edit your .bashrc
file to save copies of certain variables' values in other variables, or
even in a file, and then set up a revert function that you could call
to restore those values.
