The expectation is that BGP route announcements with an AS_SET in the
AS_PATH attribute will be discarded on a wholesale basis in the global
DFZ somewhere in the next 1 or 2 years (similar to how Private ASNs in
the DFZ were removed by large providers blocking such routes with
private ASNs).

Please do! Now is a great time to adjust that configuration to prevent
future service interruptions.
