Looks to be that e_stop latch would accomplish this?

I would not recommend that, it should be enabled only by machine enable. The reason being, if anything goes wrong on the encoders or wiring or anything else, Linuxcnc will not trigger an E-stop, it will however trigger a disable to the drives rendering them motionless.

I used a different method. I don't see how this would hinder an estop?
#============================================================
#----PINS---ESTOP---START
net estop-in iocontrol.0.emc-enable-in <= and2.0.out
net internal-estop and2.0.in1 <= iocontrol.0.user-enable-out
net remote-estop and2.0.in0 halui.estop.activate => hm2_7i92.0.7i77.0.0.input-20-not
net estop-in <= hm2_7i92.0.7i72.0.2.output-00
net estop-in halui.machine.on
#----PINS---ESTOP---END
#============================================================
#============================================================
#----PINS---ESTOP---START

Where or how did you read that ! It does not hinder E-stop, it will hinder the ability of Linuxcnc to disable the drives in many cases where it is implicitly necessary to do so for safety and prevent damage to the machine, like any missconfiguration during setup, run out of motors during tuning, in case an encoder line brakes during normal use, etc.
