There's absolutely no point in having libpt.so.1.1 or libpt.so.1 since
nothing will refer to them.

Yes.  Basically you should have three files for a shared library:

1. The actual file bearing the full version number.  This is not used by
   anything but serves the purpose of allowing upgrades to happen smoothly.
2. A link whose name is the soname.  This is used by all programs linked
   against the library.
3. A link called libwhatever.so where whatever is whatever you want people
   to put after the -l.
