Observer blocks only powering redstone dust to 1 allowed for extremely compact farms, powering air blocks allowed for all sorts of great contraptions, the extremely short tick was optimum for redstone machines that were otherwise annoying and difficult to create. What's with the neutering? Why were these marked as bugs and nerfed?

Many of the flying creations using observer blocks are now broken. They didn't work because of bugs, but because of reasonable behavior from the observer blocks.
