Namaste all,
As far as we can see such speculations on shruti oftenly drives us to the position we were before: each party holds on its own opinion. ))
But who is Param Brahma Purusham, the Supreme Delighter?
Let us consider a rich man who wants to build a large house according his delight. Will he build the house himself? Will this man destroy it himself on his delight when he wants to have a new one? Surely NO. But according his delight HE ENTERS the house HIMSELF to live in it.

A. C. Bhaktivedanta Swami Prabhupada states: "Similarly, by expanding Himself as Lord Shiva, the Supreme Lord is engaged when there is a need to annihilate the universe. Lord Shiva, in association with maya, has many forms, which are generally numbered at eleven. Lord Shiva is not one of the living entities; he is, more or less, Krishna Himself. The example of milk and yogurt is often given in this regard -- yogurt is a preparation of milk, but still yogurt cannot be used as milk. Similarly, Lord Shiva is an expansion of Krishna, but he cannot act as Krishna… The essential difference is that Lord Siva has a connection with material nature, but Vishnu or Lord Krishna has nothing to do with material nature."
Regarding the incorectness of term demigod.
Bhaktivedanta Swami Prabhupad used this greek-european word for devata/deva when he preached in the western countries.
