Hi Javier, and thanks for the reply.
I certainly do. Case usage example is the site I am working on at the moment.
The website has 400+ members (just a role in WP).
The company has 10+ board members(another role). From time to time they like to export a csv list of the members. I avoid giving wp-admin access to anyone where possible, so the ability to export from the frontend in a secure member area would be massive.
I can already do this with wpallexport, but it need cron setup, which is overkill and unreliable.
Best wishes
