This is fantastic and @zacsweers.dev deserves all the praise but it also is gonna give you a false idea of what Z is like as a maintainer and author, what the project is like, and how you might achieve something like this yourself

Square just moved Anvil to maintenance mode to adopt Metro - a DI framework built by ONE PERSON that's 47-56% faster than Dagger+Anvil.
This is what "individual developers changing ecosystems" looks like 🧵

If you happen to be in Amsterdam at the end of November, come say "hi" at the Kotlin Dev Day, where Duncan McGregor and I will be doing 47 refactorings in 45 minutes (see kotlindevday.com/program). I will also be just hanging out with Kodee on the 28th, so happy to chat or do a code kata 🧐

In the following deep dive, we’ll explore the delegation pattern used by @revenuecat.com, and how it gracefully wraps native Android and iOS SDKs.
