I think you'll experience some pushback on the assertion that that particular quote has a lot of arrogance or disdain in it. Building large legacy projects can be difficult and tapping into a thriving ecosystem of packages might be a good thing. But it's also possible to have "shiny object" or "grass is greener" syndrome.
“If you maintain a port without a working Rust toolchain, please ensure it has one within the next 6 months, or sunset the port.” If that’s not arrogant, I don’t know what is.
This seems like a long window, given to ports to say, "we are making changes that may impact you, heads up." The options presented are, frankly, the two primary options "add the dependency or tell people you are no longer a current port".
