Ah good call on those already being trailing objects on `ParsedAttr`, so it's an even bigger ask than I originally was thinking. Another good reason not to go that route yet, that's likely to be a complicated patch because of how much code changes (ClangAttrEmitter.cpp, SemaDeclAttr.cpp, probably the parser as well) and because of performance concerns (would definitely need to be tested for perf changes).
