You are missing my point, which is that if you use a Grigri, you will still deck. The rope is not slipping through the ATC, the belayer is being lifted. The rope slips at 3kN+, about 300kg of force - so your lightweight belayer (<<300kg) is lifted into the air before enough force appears at the ATC for it to begin slipping. Get it? It is acting like a Grigri anyway...

I agree tying down the belayer is not ideal, but since using a Grigri won't actually solve your problem, I thought I'd mention it
