That was one of the argument made in favor of concise methods defaulting as not enumerable: enumerable really only controls whether a property shows up in for-in (and a couple closely related reflection functions) and for-in has been essentially deprecated and replace by for-of.  That makes the enumerable attribute an obsolete feature and we should be trying to give it meaning for new features.  Hence, just always default it to true.
