Because this option already exists in moosocial and it works very well on the registration form for example.
So in my opinion we do not necessarily need a recaptcah just to send an email, I prefer to use what is included in moosocial and which works perfectly
Any plans to add this feature? You also have to understand that many niche sites simply have to put more weight on user privacy in order to keep up with Facebook and the other competitors.
Which is why it's good to limit the use of Google services.
Just my two cents. But whould be happy if you can add it. =)
