Well, that would allow patches making it through, but it would still severely increase overall size. I'm afraid more people than not also fail to cut down reply context, so we'd further see (needlessly) huge replies to patches as well. Additionally - how does one up front determine "fits the mailing list limits"? My mail UI (Thunderbird) doesn't show me the size of a message until I've actually sent it. > As a last resort > do a series splitting the re-generation out (but I guess this would > confuse the CI as well and of course for the push you want to squash > again). Yeah, unless the CI would only ever test full series, this wouldn't help. It's also imo even more cumbersome than simply stripping the generated file parts from emails. Jan
