Yes. Definitely. Eshell _already_ is very different and that's why we use
it. Bash is hardly a role model in the world of shells.

In the case of bash, the issue probably stems back from historical limitations
of VT* terminals. Something that does not make sense to emulate in modern
computers.

I don't see any use case for letting the SGR color the shell. If you want to
change you shell from a command, Elisp is your friend...
