Allright, we've been going back and forth on
http://dev.rubyonrails.org/ticket/9935, and I'd like to get some more
comments, primarily from folks using or implementing JSON rest APIs.
I personally haven't, because I tend to get a lot of pushback from
other JSON fans regarding things like this, date formats, etc.
The goal with the Rails param parsers is to allow the same controller
code to work with multiple formats (html forms, xml, json, yaml, etc).
Also, going with REST best practices would be nice too. This
question is what kept me from implementing this months ago, actually.
