I read the first couple of sentences, opened the link on my phone and found the experience a bit disappointing. Then I realised they're talking about a _desktop_ PWA, complete with a mimetype file_handler.<p>I know it's not that big a deal and the performance improvements in that PR are the real headline, but I personally really appreciate a well-executed PWA & seeing it headlined as such. Those features have been there for donkeys years, and it blows my mind how rarely they're taken advantage of properly - especially on the desktop.
