In the early 1990s there was a time when 'tech' experimentation ran wild with no guidelines whatsoever. Anything was fair game, like combos on curbs on the level of 50-50 grind to lipslide to 5-0 to shove-it out.
What happened next, let's not forget, was a period of cleaning up both style and trick selection around 1992 and 1993.
The main drivers were skaters on all World companies and later also Girl/Chocolate, Alien, and early Foundation with Steve Olson and Ronnie C. They made a point of what constitutes a proper 5-0 grind on a ledge (don't drag the tail) or nosegrind (don't skid the nose, or it's a snow shovel). They also placed a focus on technical finesse with all the fakie 5-0 flips and techy manual tricks. And as a result, street skating looked much cleaner and trick selection overall improved.
Today we're back in 1991 and people don't know any better. They think it's 'creative' when skaters pop a front foot impossible out of a 50-50 grind at low speed. Or grab their board and throw in some 'freestyle' moves. Sooo mind-boggling (to the longboarders turned influencers/video bloggers that now comment on skate videos in the absence of expert media)!
And in a way, that's cool. The mid-1990s scene was a bit 'cool guy' and 'vibey' and 'cliquey' anyhow.
But personally, I'd much rather see folks continue down the 'clean' path than the 'gross' variations in their trick selection that were left behind in the process of evolving the art of street skating.
