Damned, I had a brain fart!
I wrote the previous thinking that you were talking about the 173 signal gate module.
For the gate delay in 172 I actually find use. It's always good to have a possibility to extract a pulse from any signal. I don't use the delay much, but the threshold & gate length I do use.
If you don't want to keep it.. I'd build a kick-ass LFO in place of it to control the phaser & delay.
