How can we improve WHMCS?

Hello, I have just thought of a suggestion on how to make the WHMCS platform more user friendly,
Would it be possible to add a feature where you can "Invite clients" to join your hosting platform?

So when "invite client" is clicked, a box will pop up, to enter the clients email address which will then automatically send the client an email with a link inviting them to join the platform.

I think this would in a way help with GDPR compliance as it will give the client the option to sign up or not as at the moment you have to manually set up a user profile unless the client registers themself.
