Change in default xml, rjs respond_to templates that Rails l

Not sure if this is the right avenue to discuss this but I couldn’t
find anywhere to ask this question on Rails Trac.

Regarding this latest changeset: (Change default respond_to
templates for xml and rjs formats.)

Does anyone know the rationale behind it? I can imagine there would be
an announcement in the future about this backward compatibility
breaking change, but I am living on the edge for one of my projects so
I’m curious.

Also, if any Rails committers see this, maybe you can consider making
it fallback to the old defaults and (throw a deprection warning) if
the new defaults can’t be found so that there is no need to either
rename the RJS templates or tell Rails which template to use (using
render :action => “#{action_name}.rjs”)?
