Support arbitrary links (with a warning for novice users?)

[Jonas De Kegel]

From the FAQ

Will this allow anyone to link me to any url on my instance?
No, this is not possible. All links and their parameters are pre-defined in this website and in the "my" integration in Home Assistant.

I'm assuming that this decision was made to protect more novice users? (if not, please clarify why)

Could we consider allowing arbitrary redirects after all, making it easier for add-on/custom component developers (or anyone trustworthy really) to provide support (amongst likely a lot of other use-cases)

I'm open to provide a contribution for this if it would be accepted.

Thanks for considering!
