(Image alt: 3D rendering of one of the new spring variants. It is much shallower and wider than the previous designs, featuring a water pool around 8 blocks in diameter, surrounded by a sulfur and granite ring. It also extends down into the ground with tuff and granite.)
Of course, the one pictured is only one of many variants, you can see a full list here:

I personally think it’s a good step in the right direction. It’s obviously a response to all the negative player feedback as of late regarding the original spring designs and I feel like it addresses it well.
something i think people miss in the replies here is that Minecraft is largely a sandbox game.
when it comes to worldgen, some features are meant to serve as setpeices to build around and explore; large lush caves and the newer mountains are great backdrops to build in, and structures like ancient cities are awesome to find and loot.
other features, however, are meant to inspire players to change them in their own way. the most obvious example of this are villages; some players sprawl them out into bustling towns, others shove the lot of 'em into a large trading hall, and some just make their own house to move in.
there are even secret villager types in biomes that don’t have them (jungle + swamp) to encourage players to set up their own.
villages would be less effective, though, if they were already beautiful metropolises that players didn’t ever have to change. the most Mojang ever did towards this were the changes in 1.14; even then, they were careful not to overdo it.
so sure, there are a ton of ways Mojang could make sulfur springs better past this. they could sprawl them out more, have a custom structure nearby using the new blocks, make the springs have richer colours…
… or maybe you should go out, find one, and build what you want to see.
