There are also ways to abstract the files on disk such that it appears every module has its own copy of “foo.so” but they’re all the same bytes on disk. Using content hashes for example. I believe this is how pnpm works.

I don’t buy the shared libraries solve problems argument either. Lots of software are pinned to a specific version anyway so just because some security update has come out for a shared lib doesn’t mean it will work with all your other software.
