JSON string says c2array, will it become c3array someday?

Hello;

I am passing the JSON string of an array made by using AsJSON to a function. As an error check I want

to be sure my string is an array. I can see the JSON string {"c2array":true,"size":[2,1,1],"data":[[[257]],[[264]]]}.

Will the array addin always generate "c2array" or (since we are still in c3 Beta" is it going to become "c3array" at some point?

thanks for your time

yours
