Could be: depends on the precise semantics of spawn, which I don't know.

It's fundamentally tricky just in the same way as your proposed
"namespace cleanup": if you undefine a function that's still registered
on some hook, process filter, ... you may get subsequent errors, some of
which may render Emacs completely unusable.
So it's risky to call unload-feature on a random package, but it's not
too hard for a package to make sure it survives unload-feature.
Tho currently, there are some significant shortcomings (IIRC there are
cases where the package's autoloads aren't re-instated, for example).
