iiuc this will change which distros we can support - ie it will make the envoy binary that is produced incompatible with more distro/versions

What do we need to do to make forward progress on this? This change will allow us to get C++20 support in Envoy, which is required for at least the Google URL dependency.

well iiuc then there is not much we can do other than create some path/code for legacy toolchains - this would already be a great thing and would resolve a bunch of tangentially related issues, but its not trivial

without that its more of a political decision about when we stop supporting which distro/versions

What if we only used the new 22.04 image for gcc CI, but use the old imagine for everything else? Would that help?

with current setup it would mean separating images/build/etc and corresponding images in envoy

Would that be easier/better than trying to just use 22.04 for everything?

if we want to support multiple toolchains its not going to be easy whatever way we do it - either in terms of setup or maintenance

i think there is a ~right way to do this - not that i necessarily know it at this point, and probs that is the way to pursue
