Proton Captcha Support?

[KensonPlays]

This could be an amazing addition for a privacy friendly captcha (in addition to Captcha). It is also 100% GDPR-compliant.

That is, once they make it available to others. It states at the bottom of the page:

We look forward to hearing your feedback and suggestions! In the future, we may also consider making it available for third-parties who care about privacy via an API. To find out more, you can contact us at enterprise@proton.me.

Proton Captcha seems like it's not very well known, but I'm moving to the Proton ecosystem, and I'd love to add support for this on my website.
