They are mostly built over Eth Blockchain and have ERC-20 tokens as their native currency and you would easily find lot of discussion about them on Altcoin board and if you say each separate board dedicated to all of them as sub-board then it's not possible and logical at all.

Suppose if theymos take into consideration your advice and have such boards then what if the trend is over and no more projects are into the market? Then what delete that board? This is all irrelevant as they are sub-topic of trading and altcoin board as @mk4 have suggested to you.

Having sperate boards for taproot and other technical updations in bitcoin seems right to you?
