Yo bros, if blockland did make it to steam it's not like we wouldn't be able to get addons anymore? Like over half the games on steam are mod-able w/o steam workshop and a bunch use launchers, too.
Anyone making the argument "more stupid people/more stupid servers/overpopulation of good servers" is dumb. There's thirty something thousand keys in existence, and, say, around 2500 active players at any given time(probably more but whatever). There's stupid people, there always will be. More stupid people means more cool people. Yes, some of the current "good" servers may have the blue name a lot of times but there would also be A LOT more of the "good" servers to boot. It's not like having more than 150 players on at a time would hurt anything.
Now of course that resides on the big "if", but still.
