Can you explain why a proto for each Filter is necessary? I'm assuming this is for being able to pull config info from the XDS proto values? Mostly just want to make sure I understand what is happening here. (Also leads me into that fact we should write some docs on "writing your own filters" 😄)

Looking at Envoy, I assume this matches up to something like:

Yes that's the case it matches envoy's filter proto files. XDS has a filter chain proto message that's a list of these config messages one per filter. Then on our end after receiving we transform that XDS filter chain into our own e32fb6d#diff-07a585ddcc9ea470eb22742d985007bb1483e42bafd05d660ed3ec5294cdb1d0R142-R154

Random thought - this seems like a lot of boilerplate. Macro time?

That could be the case, not sure what a macro here would look like and I don't think it'll be trivial to write if possible, since the heirarchies are arbitrarily nested and the macro would need to figure out where each include goes and how to split the raw string to figure out the module components
