Having watched countless instructor Chad BCG Autopsies, I should have thought of that myself!

As long as the staking covers the bevel on the screw, I'd happy with that.

Once you own a staking tool, every staking job looks suspect.

That picture by Bounty is the look I would have expected. The OP stake looks minimal, and maybe insufficient. I'm not an armorer. I defer to the experts.

I agree (from my layman's perspective). You want the staking to look like the lock screws on old German Mausers, physically preventing any rotation.

It isn't supposed to stop rotation in this case. It is to stop a broken screw from banging around inside your gun and doing more damage.
Can they be staked further or is this a return?
Yes they can be staked further.

From what I've read, staking serves both purposes - preventing broken screws from banging around AND also ensuring that the gas key does not come loose (causing malfunctions).

I was always led to believe proper torque keeps the screws tight, and over staking can break screws.
YMMV
I sent images of the staking to Geissele - I hope to hear back from them. I bought the BCG after watching instructor Chad's BCG video on it. Normally these are around $280, so when I was able to get one from Primary Arms for $200 shipped it was within my budget and I purchased it. Now that I have it I am disappointed with their workmanship, if you look closely you can still see grind marks on gas key as well. Not sure if that is normal, but I never have had any workmanship issues with the hand full of SOLGW BCGs I bough for $109 when they were on sale. I will let you all know what Geissele has to say.

In my opinion, I think the staking is sufficient although as a disclaimer, when I see a stake job that's appears a bit weak, I have the tooling to address... Gas keys and staking doesn't worry me much any more (thanks SOTAR). Great tool....

This is correct.
If you're really concerned about rotation, in addition to the reverse torque test, simply take some paint and mark the fastener and gas key. It's a good visual for fasteners when you are maintaining your rifle.
