Well, I think I've cracked it - after a few weeks of on-and-off work on making my webmention sending not spam everyone (see https://www.jvt.me/posts/2019/10/30/reader-mail-webmention-spam/ ) - it's now not re-sending them if they're successful. This is a good first step, but I'll be improving it to re-send if the post's data has changed since last time it tried (in the future).
Note that this isn't quite done yet, expect it to be live tomorrow perhaps.

Welcome, Matt!
Thanks for blogging about your experiences, it's really great to see, especially because it was through me you've been interested in it!
I'd heavily recommend https://github.com/PlaidWeb/webmention.js/ by https://beesbuzz.biz/ as I currently use it on my site and love it because I don't need to rebuild my site to show new Webmentions, although it does mean that my viewers need client-side Javascript.

As an FYI it looks like the issue with minification wasn't due to GZIP but actually the minification of the CSS it does, which would likely replace things like .h-card

A great writeup of a huge event - when I went a few years ago I was bowled over by how much time I'd need to spend to see everything I wanted to (hint: it was more than the few days I was there)
