[xwiki-devs] [proposal] Add velocity api which is deprecated so that templates can be made to log a deprecated warning.

I would like to start deprecating templates which are no longer used and I think the right way is to make the deprecated template throw a warning to the logs when it's called. I am proposing adding a service which does nothing but is deprecated. Templates which we deprecate will have this call added and then users of said templates will have fair warning that the template will be removed. Not knowing what the convention is I will blindly suggest: $services.velocity.deprecated() If anyone has a better name, I'd like to hear it. WDYT? Caleb
