extention of autorouter in ci4.2

Hi.

I'm working on a CI4.1.9 application, which extends the default-handling of auto-routing (existing since CI3) more deeply.

Yesterday i've read about the problem, which comes with that handling concerning creating vulnerable apps where controller filters or CSRF protection are bypassed . On shorthand i decided to upgrade to CI4.2.3, but stumbled over these problems:

• both new classes for auto-routing (AutoRouter and AutoRouterImproved) can't be extended, since they are both finalized
  
• and they also seem to be instantiated directly via new keyword (e.g. https://github.com/codeigniter4/CodeIgni...r.php#L136) instead by some Service-method or equal
  

So my questions would be:

• is there any way, to extend new auto-routing handling (except writing a complete own handler for this)?
  
• if not, is it maybe planned for a future ci-version, to establish the instantiation more dynamically like via service-method, etc.?
  

Thanks in advance.

(I'm willing to share more info, if you need anything ;-))
