Whoops, that was a typo before.  Pin 8 is used for the local control.
Snipping that will only disable local control.  Pin 6 drives the triac.
That line is essential.  If snipped there will be no on/off control at all.
The dimming phase control is inside the IC.

It might be possible to extend the pulse coming out of the IC so that if
there is ANY pulse at all, the transistor will remain on through the
beginning of the next cycle so the unit will switch on right after the zero
crossing.
