Yes... yes we are, actually.
Because Reason only "became a DAW" as of Reason 6.0**, and even then it couldn't host proprietary plugins (RE's) until 6.5 came out. That was 2012, just a paltry 7 years ago. Meanwhile, virtually every other DAW on the market had a 17-20+ year head start and could host ANY (VST) plugin. And we couldn't host VST in Reason until 9.5 in 2017, just 3 years ago (and we still cannot host VST 3 in Reason DAW proper despite Reason Rack Plugin being a freaking VST 3 - LMAO)!!!
So when you ask questions like this, I think it's important to understand just how far behind Propellerhead (and now Reason Studios) was from the beginning. The sequencer and DAW proper still lack many basic DAW functions that literally every other DAW on the market has had practically from the start. And now Reason Studios have went all in on making Reason a VST rack plugin, so... there's that.
Look, I'm one of Reason's greatest champions - it's still my DAW of choice, but even I can see that Reason DAW proper will never, EVER, gain the sort of usage and market saturation as DAW that have been on the market for 2 decades plus, just because it's not in Reason's design ethos for RS to throw every feature missing into the sequencer. Even if they did today, it's not going to make a huge amount of people jump ship, IMHO.
** Ignoring Record + Reason 5, because that was just a confusing mess IMHO.
