That's the case *now* (esopecially if you consider rrthe need foir an
unreleased version of Windows to open gates in the walls of the "walled
garden" you described in an earlier thread.
But maybe Microsoft will stay serious this time and offer this as an
end-user useable tool. Even maybe with a wider choice of Linux
distributions (it *is* at least possible
<https://github.com/RoliSoft/WSL-Distribution-Switcher>).

"Snappy is a bit hyperbolic (consider the machine I was running it on...),

In the Jupyter notebook. It worked. I can't recall having tested it in a
terminal windows nor in a mintty console, but I would have probably noted
if it didn't work...

I don't know if a "stock" Windows machine even has such a program : .png is
quite foreign in the Windows world, where the natives are expected to speak
.bpm (yuck !) .wmf (yuckier :-) or .emf (yuckiest...)

:-) It's a start. Don't despair... More seriously, it's the
IDE-posing-as-an-editor that sold me (a couple decades back) to Unix. It's
a marvelous way to work simultaneously on computations and on their
description in plain globish (=what passes for English in the international
scientific community) or French (it still exists, you know...).
If you cold tell me more about this "sage_shell_mode"
Better ask Sho Takemori <https://github.com/sagemath/sage-shell-mode>, the
author...

I think that the problem is bound to the prompts : it happens exactly the
same way in Sagemath installer + Windows port of Emacs as it happens with
WSL + Ubuntu + my self-compiled Sage + emacs25.
Probably on the emacs-lisp side of the things... I'll open an issue on this.
