Hinting That More Seasons Could Come
The Television Academy’s criteria for limited series state: “The program must tell a complete, non-recurring story and not have an ongoing storyline or main characters in subsequent seasons.”
Because it doesn't qualify as a miniseries.
Although the article then goes on to say that "Echo" (and similar) did qualify as a miniseries.
Sounds like Disney and the awards need to just clarify things.
ALL THAT BEING SAID, of course we're getting more Agatha, it'll just have a different title.
