That seems to be the case. Also, possibly the use of WKC 65535:666 has not picked up much. We observe that out of a 
total of 264,557 unique {Prefix, AS Path, Community = Any:666} seen in a whole day's worth of BGP Updates from RIPE-RIS 
(July 15, 2021), only 21 are with 65535:666. See slide 12 here:
