1♦ is cleary the right system bid. I suspect you will find books with similar hands opening 1♦ and i would rebid 1♠ over 1♥, placing a club with my diamonds if need be
So of these rules are too limiting.
to have a 1♠ need 4 ♦ to bid. This could end up forcing responder to go to 2 level in search for a fit or missing a spade fit entirely if responder doesnt have the values to act over 1NT
To require a 2♣ also to show 4♦ is limiting. There are a lot of 1-4-3-5 hands where you may not want to rebid 1NT with a singleton, so want to show your club suit, so partner can evealute their hand and your not stong wnough to reverse into hearts
1NT is a reasonable opening, with Kx we wouldnt even queston it.
Sarcasm is a state of mind
