@innocenzi changing the Route interface is a breaking change.

The only mention in the docs about making your own route classes though is this: https://tempestphp.com/2.x/essentials/routing#group-middleware

While Tempest does not provide a way to group middleware, you can easily create your own route attribute that applies or excludes a set of middleware to a route.

How do you feel about it? Should we target 3.x?

I decided to merge this for 2.8: a poll on Discord shows that there's only a handful of people who would be affected by the change, and I've added a rector to make it easier.

The tl;dr is that Route classes must now also be writeable, so if they are declared readonly, that should be removed.
