OK, let's talk about this broader issue.

Let's start by describing the use cases for this feature, and please
describe those use features in Emacs terms.  IOW, instead of "act as a
real Unix shell", please describe what you'd like Emacs to do with the
file descriptors in terms of Emacs functionality, like display or edit
text, send or receive text to/from a subprocess, etc.  Also, what kind
of descriptors (i.e. what kinds of files/devices are they open on)
would be useful in this context?

I'm asking for this because Emacs is not a shell, and its repertoire
of features is quite different from that of a Unix shell.  So looking
at a shell as our model is not necessarily useful.

Thanks.
