Having the template namespace protected to all anons is a good move. There is usually no reason for an anonymous editor to edit templates as most templates don't generally need to be edited in the first place (the exception is infoboxes, but such edits are usually just limited to fixing bugs by the infobox creator on each respective wiki). Anons generally don't edit in non-mainspace areas (excluding blogs and forums), so a good move :)

Don't like the idea of being harassed with a banner notification telling me to use portable infoboxes. I don't feel any reason to use them, as the infoboxes I code on my respective wiki's work just fine in mobile and desktop.
