The majority in Taiwan have always preferred status quo. That's what happens when you border a much larger neighbour that would see any overt move to officially declare independence (as in rebrand as Taiwan officially) as justification to invade.

That's just the Taiwanese being self-aware to notice large power disparities and not wanting to rock the boat. Actual unification support with China polls about in the 10-15%. Lower than the "move to independence" bloc.
