Regardless of who actually prepares and signs their name to the construction documents, I as a plans examiner, require the same amount of information and design to be provided on the plans. This includes conductor sizes, conductor types, ground detail, overcurrent protection sizing and types, load calculations, short circuit analysis and available fault current calculations, equipment AIC ratings, selective coordination analysis, so on and so forth.
As indicated by Mr. Kuritzky, the larger the system, the more complicated the above items become. Most electrical contractors and architects are not up for the task, not because they are unskilled or not smart enough, but because it is typically beyond their scope of training and education. This is not to say all professional engineers are up for the task either, as I have rejected many plans on first submittal for lack of compliant design of the electrical system.
That said, I do agree the matter needs to be resolved for proper enforcement and correlation of the laws and rules we must all follow.
