FWIW, git now has options to ignore such commits. In a big codebase each big codemod sha should be added to the blame ignore file .git-blame-ignore-revs. It's supported by GitHub out of the box https://www.stefanjudis.com/today-i-learned/how-to-exclude-c...

HN discussionSafari and Chrome now use a combined cache strategy using the URL of the resource and the top level domain of the site loading that resource as the cache key. For scenarios that were previously popular like using the jQuery CDN, you won't get the benefit of the user having jQuery in their cache from another website. You will however still get the proximity benefit you describe. CDNs are obviously still quite useful,…

HN discussionThere was the use case at one point that serving a version of a popular 3rd party JS framework from a CDN would result in the likelihood of that file being able to be served from the browser's cache, because there would be a decent chance the end user had visited some other site that used the same popular framework. That no longer works, see https://www.stefanjudis.com/notes/say-goodbye-to-resource-ca... and https:/…

HN discussionI’m sure it’s not the only factor, but loading JavaScript from external domains (like from Google) changed from being good for caching – i.e. faster web pages – to being meaningless and usually slower: • https://www.stefanjudis.com/notes/say-goodbye-to-resource-ca... • https://wicki.io/posts/2020-11-goodbye-google-fonts/

HN discussion> jQuery is ≈30k gziped and most likely already cached from CDN. This part isn't so true in reality anymore, due to revised browser caching systems[1]. Doesn't mean you shouldn't use jQuery, just that part of the benefits of a centralized CDN are no longer a factor and it's a lot more sensible to self-host. 1: https://www.stefanjudis.com/notes/say-goodbye-to-resource-ca...
