I think the perception of short scale basses has been changing for a much longer time than that - the Epiphone Allen Woody Rumblekat bass came out in the early 2000s I believe and is still in production. Even further back, Sheryl Crow playing a Guild M-85 drove up interest in those - but there's a backstory there with her bassist on Tuesday Night Music Club (1993) using the earlier hollow-body M-85 with Bi-Sonics (hers was the later one with Guild humbuckers) and a growing fascination with those, leading in to the Fred Hammon Dark Star pickups, which I think was part of the fascination with the Guild short scales of Jack Casady & Phil Lesh. In recent years Guild has reissued the both the Starfire & M-85.
Also in more recent years, maybe the reintroduction of the Fender Mustang bass? There were MIJ reissues, they have a more recent MIM version with PJ pickups (which I find hideous but the "average" bassist seems to like), and now there's a Jason Meldal-Johnsen signature Mustang.
In general I think there has always been a general perception of short scales as "beginner instruments" or "for girls" when actually, people who knew how to play them (regardless of gender) knew that they were so much more.
