Yes, of course, but... the meaning which numpy attributes to Ellipsis does not have to be the same in other libraries. Otherwise this meaning would have been embedded in the interpreter itself, while it hasn't.

The meaning which numpy attributes to Ellipsis is also the meaning that mathematical notation has attached to Ellipsis for a very long time.
