They wouldn't do a whole event just for Airtags (I would think...). More likely the event would be tied in with overdue iPad Pro refreshes, which are mentioned here as being supply constrained. Long way to say yes, this could be part of why it seems like the unannounced but expected Apple event remained unannounced.
