No, they are both URIs. There is no such thing as a directory. There
such things as collections, and the latter URI is a collection, whereas
the URI without a slash is not. Apache's filesystem does not allow two
different URIs to access the collection because they differ in
which will result in client failure if any later response contains
relative URIs.

The server must send a redirect. Clients that do not receive a redirect
(because a published version is broken) are not really helped by not
receiving the redirect -- in fact, it causes them to be substantially
slower and buggy in later requests. That is why we default to sending
a redirect, and no this has nothing to do with the GET method.

Our responsibility is to encourage client developers to find a clue
and implement HTTP correctly. We only provide workarounds when they
are absolutely necessary for deployed applications, and even then only
when they are limited to that application's version.
