Custom profile field types

I have filed TE-19697 as a feature request, but this would not be a 14.0 item and would be potentially prioritized for a future release.  It would also be helpful to understand why this is needed along with a detailed example that can be added to that story.

So the ones we have created and used in the past were for better rendering and editing experience for things like social media profiles, i.e. displays an icon next to it, if you put in your url in or just your id it formats it nicely etc.
