I'm sorry, but no, that's not the use case. Its mere existence is to be
able to have views that not use a template to render content versus
views that have a template, without the complex, hard to explain
stratetgy for finding an implicitely or explicitely associated template
and checking there's no render() in that case that we had before.

I looked up a thread of quite a while ago where we discussed this before.
Even after re-reading the thread some nuances for such a component are
not completely clear to me. I would in any way encourage to write a
megrok.* package to extend Grok with such a component! Eventually this
component could then go into "core" Grok of course.
