Because rsync semantics around the trailing slash are a little confusing and unusual, it's pretty common IME for people to intentionally explicitly define paths to the file with rsync, in order to avoid having to look up which way they need to write the target path.

Use a dot after the trailing slash and there is less confusion. "Blabla/." means "(everything) in the Blabla directory". Fairly self-explanatory/un-confusing and no need for "*"
