I agree that using template-based forms makes so much sense that it is
worth taking the performance hit by default, but I have a different
proposal for what those people should do who need "absolute speed" in
template rendering: use Jinja2 instead of DTL. Several adapters are
available that make Jinja2 work as a Django template loader (e.g.
[https://github.com/jbalogh/jingo jingo]), which means that it can be a
drop-in replacement for DTL (apart from needing to update template syntax,
of course). I think it's easy enough to switch to Jinja2 if you really
need the speed that it is not worth us maintaining two separate widget
rendering systems in Django.
