Can I just say: thank you for posting an xcancel link and not linking to X directly! I forgot Xcancel was a thing, I might actually start using it occasionally now.
There is an open source web browser proxy thing called finicky [0]. I use at work that lets me redirect urls clicked in other apps like slack to specific browers (firefox / chrome) or even specific chrome profiles. It'll also allow you to rewrite the urls.
Its pretty widely used on HN from what I notice.
I noticed that xcancel links are rewritten to x.com more often than not, probably due to the fact that xcancel will not last like xitter, nitter and all the ones before it.
I hope that archive services implement preserving twitter content.
