Yes, one may indeed want those things. In particular, *I* want
multi-module files.
I do not want to move towards a Java-style approach where the package
nesting structure needs to match the file/directory nesting structure.
Being able to declare nested modules within a file is very useful for
flexible namespace control.
I like our current support for nesting modules in files, and breaking
them out into separate files as one wants.
But then again, I also think that the current approach of { `extern
mod`... `use`... `mod`... } is pretty understandable once you, well,
understand it. My main complaint has been about the slightly
context-dependent interpretation of paths [1], but that's pretty minor.
So perhaps I have the wrong point-of-view for interpreting these
suggestions for change.

What would you do?
Have no structure (no mod)? Or automatically create it from the file
structure?

This may be limiting at times, possibility one may want multi-module
files and multi-file modules. But this forms a good, simple base
(anyway, we have mini & maxi modules & code files, whatever the
logical & physical organisations). Another point is that very often we
have package (I mean crate ;-) sub-dirs which are not packages
themselves. Then, as usual, we'd have a special code file representing
a package at its top dir (the same name as the package, or a magic
name like 'main').
Then, module sharing is code file sharing, and package management is
dir management (trivially .zip-ed or .tar.gz-ed, and then the name
"package" is here for something).
