I've noticed this has been implemented in the latest release, and I've tested.
Although a nice feature added, I think the initial point made by Ivan was missed.
When using an opening and closing tag for roles, we are refering to something like this:
[ISINROLE:ADMIN] display this content to only roles listed in admin [/ISINROLE:ADMIN]
[ISINROLE:REGISTEREDUSERS] display this content to only roles in registered users and above [/ISINROLE:REGISTEREDUSERS]
This would be a nice feature to have because when creating the template for users, fields can be wrapped and diplayed ONLY to certain roles of the site
IE: I only want email addresses displayed to logged in registered users, or I only want addresses shown to logged in registered users, etc, etc. but the rest of the data such as photos, biography can be shared to the public.
Another good example for this would be [ISINROLE:REGISTEREDUSERS] [ADDTOFRIENDS] [/ISINROLE:REGISTEREDUSERS] and if you're not a registered user, the "Add To Friends" button will not appear on the profile, it will remain hidden....................
