Yes I think so. When I was testing ob-shell today I initially tried
with an M-x shell session, and I was surprised it didn't work.

But I also noticed another prompt-related issue: conda doesn't seem to
work in ob-shell sessions anymore. That is a bigger problem for my use
case.

I guess, SSH doesn't work with the current implementation either.

This isn't a feature I need, but I have seen others make use of it in
the past, e.g. [1].

That is a really neat idea.

Sadly, "conda activate" doesn't seem to work in here-documents :(

ob-shell is really tricky, with so many cases
(bash/zsh/fish/Windows/etc). Perhaps ob-shell could have a main
"batch-like" implementation (either here-documents, or source'ing
tempfile, or wrapper function), but also have a fallback line-by-line
implementation for certain edge cases?
