Why not use a kext for Broadcom Wifi in Sonoma?

As I understand it:

1. Broadcom wifi drivers were removed in Sonoma and an existing workaround requires SIP to be disabled to inject these drivers.

2. On the other hand Intel Wifi is enabled with a kext and an appropriate entry for said kext in config.plist.

Is it possible to enable Broadcom wifi without disabling SIP? Could this be done like the Intel wifi by develop / extract a Broadcom kext, add it to the kext folder and add an entry to config.plist?
