Rename {{temp|ar-numeral}} to {{temp|ar-cardinal}}?

Where did this consensus come from? Is this just your take on things (not that I'm objecting necessarily)?

I recently edited the Eastern Arabic and Abjad numeral symbols so the heading says ===Numeral symbol===. If you think this really should say just ===Symbol=== then I won't object but would ask that you make the change yourself since you're comfortable making global search/replace changes and I'm still figuring this out.

I don't really remember. I think the consensus was "this mess needs to be sorted out" but nobody could agree on how. Eventually someone (me I think) came up with an idea and it was adopted, but I don't remember the details. If you do a search for number/numeral in the Wiktionary: namespace you'll find the countless discussions about it.
