5 minutes work with a 2mm drill bit Vs. the risk an engine/gearbox/rear axle failure. I have rebuilt an A7 motor (not mine) that dropped its sump plug at high speed. Knackered big ends, crank with some scoring, bores needed a hone and new rings.
I always lock wire drain plugs. On an A7 with a tin sump. there's enough metal on the return fold of the flange to make the lockwire off to. Otherwise, there's always somewhere. This with the lockwire going round one of the new fangled additions on my special's rear axle.

Otherwise, Just cross drill a handy bolt head, like this one I did on Sue's Fiat Giardinera.

Of course, it might just be alright on the night; here's the sump plug I took out of Sue's Giardinera. A previous owner had ripped the thread out of the ally sump, cobbled this item up, bashed it into place and sealed it with a big gob of silicone.

I rethreaded the sump plug hole to the next BSP size; the car hasn't rejected this foreign component as yet.
