Will we have an alternative for "middleware" in CodeIgniter4?

Are you thinking something like https://bcit-ci.github.io/CodeIgniter4/g...lters.html ?

The subject of "middleware" has come up within the council, and disregarding the misuse of the term (at odds with enterprise development interpretation), the way "they" handle it is incompatible with our HTTP request implementation. The notion of request handler chaining is getting a bit of traction, though. All we need is time, lots of it!
