Functionally this

Multi-envoy does not correctly support runtime flags or deprecation stats due to #19847 being incomplete. It can still handle proxy traffic client - L1 - L2 - upstream as shown in test.

LGTM. I think it might be a good idea to also get a review from someone more familiar with Runtime in order to assess the implications of making it no longer a proper Singleton. But it looks good from my perspective.

I would have expected this to delegate to InstanceImpl::runtime(). But does that not work because ValidationInstance does not extend InstanceImpl?

exactly. arguably I should do the same restart flag checks here, but I'lll get there in the PR I flip the runtime guard true by default.

nit: destructors usually come before other methods. I'm mildly surprised this doesn't need to be marked override, but C++ is weird.

Nice!

Would it also make sense (perhaps as a follow up?) to have a test in which we create 2 distinct Envoy instances, both in front of the same (or different, I suppose) upstreams. Then we could verify that requests flow through both, close one, and verify that the other still works?

yeah I also plan on having tests where I tear down the L2 and verify the L1 500s correctly, or tear down L1 and make sure I can talk directly to L2 -> client, to ensure lifetime issues are really sorted and regression tested against.

Having some tests that verify different shutdown ordering would be useful I think, just to make sure that they can exist independently of each other

yeah for sure this gets second pass review, even with minimal code.
The impact of not having a singleton runtime should be documented in the PR description, and should be moot once the other PRs I have in flight land, at which point there is no runtime singleton access in the code any more and I can fix up the final tests and flip the flag true.

Seems reasonable to me

What is the behavior if the two instances are run with different options? e.g. if the log output path is different between the two

re logging: unsure. Added to my list of things on envoyproxy/envoy-mobile#2003 to do in follow up PRs as I don't think I can get it done today :-)
