Ad 1:
As of the cited versions, nothing will be done if you use LOAD to load a module
that is already loaded.

Ad 2:
The change was a bugfix that was applied to the development version (so it is included
in 9.0 and later) and was backpatched to 8.2, 8.3 and 8.4.

If you want to know details about a change like this, you'll have to dig into the
git logs and possibly the code.
The commit was 602a9ef5a7c60151e10293ae3c4bb3fbb0132d03 in master,
57710f39cc55cba1e98c718300a811aadacec7c5 in 8.4,
5927d9f642c4cf6233e5fedd3468087995c00523 in 8.3 and
22f77b0f9db1220789b262cda6dccad49d031643 in 8.2.

Ad 3:
Because the same fix was applied to these three versions.

It is safe to assume that a problem that was fixed in 8.4 will also be
fixed in 9.0 and above, even though the 9.0 release notes don't explicitly
mention it - they mostly contain new features.

When reading up on the changes between 8.1.2 and 9.3.6 (a daunting task)
you can usually limit yourself to reading 8.2, 8.3, 8.4, 9.0, 9.1, 9.2
and 9.3. This should cover all behaviour changes that are likely to
affect you.
The minor releases should not change behaviour other than fixing bugs.
