That’s half my point. Android is already open for things like this to work. iOS needs to be open and accessible. If Apple allows mirroring in the EU , the regulators will want it accessible cross platform like Android is and not locked to the iOS only works with Mac like they currently have.

I know there are third party tools that mirror iOS to windows, but as I understand it , they all use old or hacked methods that frequently break with updates. Similar to open source airplay receivers using old methods and only supporting audio.
