Though some of those ideas have been proposed long ago (most ideas in general have, realty, there are a lot of idea posts) it’s still fruitful to continue commenting and voting on old ideas, in my opinion.
The Alchemy Lab coming this year is based on this thread that started all the way back in June 2017. So it’s certainly not unheard of for the game designers to mull an idea for a long while and ultimately implement it.
I’d like to think the ongoing support expressed by fellow players in that thread helped.
