ELF libraries have a combination of version numbers - major, minor,
and some have what the docs term "teeny".  What is actually linked in
at run-time in the ELF case is the symbolic link - i.e.
the major one.

So although there may be many shared libraries with different minor
numbers, they usually retain the same major number (in general, unless
there's been an ABI change).

How do you propose to provide many instances of a library with the
same major number in the same directory?

I'm disappointed that you think that package views are complicated. 
To me, they're simple, perhaps ugly, but very functional, and very
little extra overhead in terms of user intervention, space, speed, and
installation overhead, but I admit that my outlook isn't exactly

However, if you read the documentation, you'll see the other systems
that have been proposed, and you will be able to compare them to
package views.
