The 1-tick redstone output trick using pistons still works, but apparently it isn't enough to power the next piston, which would create a T-Flip Flop switch
i'm attaching a video to give you a clear representation.
I tried placing a redstone torch next to it and destroy it quickly, so i got a 1 tick output.
manually it worked, but for some reason it doesn't work with the piston

I believe the monostable circuit pictured only works if the redstone dust and repeater are switched. The pictured design doesn't work because a monostable circuit needs a one gametick signal and repeaters give a minimum of a two gametick signal.
I just tested in version 1.12.2 and noticed the same behavior. It works when the when the output of the monostable circuit goes through a repeater before it activates the piston that should drop the block.
