I'm not sure why anyone bothers posting these sorts of hands. Partner made a stupid bid. He had a clear pass of 3C, except that he is the sort of player who thinks that he has to make every decision for the partnership.
Even if partner's call is ridiculous, there's still value in discussing what the right call is in the cases where partner's call wasn't ridiculous. Now maybe one shouldn't bother posting partner's ridiculous hand, that's another story.

As an example, say we bid 4C. Partner is supposed to bid suits up the line. So what if he bids 4D? Having found our fit, do we override to bid 4S anyway? If not, why not? And, if yes, why waste time with 4C? Indeed, logically if we bid 4C then 4S, denying interest in the red suits, we should have some mild slam interest, since we were planning on 4S from the outset but chose to cuebid first.
If partner bids 4H over 4C, why would our 4S call mean that we have longer diamonds? We didn't know he was bidding 4H rather than 4D, so our 4S call has the same meaning as if he had bid 4D....a hand too good for a direct 4S.
Now, if we had 4=4 majors, we'd not be conveying slam interest, since we'd bid 4H over 4D to keep looking for the fit, and we'd pass 4H.
I think it's really weird and suboptimal to bid diamonds up the line in response to cue bid. I mean how often does partner care if you have diamonds? The most common hand for the cue bid must be equal length majors, so surely you should bid your lowest 4 cd major if you have one. That makes life easier IMO. With the most common hand partner can just pass. If your 4d denies 4 cd major, then partner can bid *either* major as the slam try too strong for just 4M. Or raise D, etc. Or maybe 3c-x-p-4c-p-4d-p-4H is supposed to be 5-5 majors to cater to some cases where doubler is 3352? I don't know, I haven't really ever discussed this and it doesn't show up in books.
Correcting hearts to spades can show 4 cd spades and diamonds, can correct 4s over the cue to 5d with hearts and diamonds. The only thing you give up is the 4 level slam try in spades if partner has hearts. The question is whether making lower level slam try is more or less important than getting to best game. The adage is game before slam, so ... You are giving up the slam try in hearts, so is it that bad to give up the slam try in spades?
If it goes 1c - x - p - 2c, don't you bid a major in preference to diamonds? Why should this be different?

IMO our main aim should be to reach a playable game, rather than find a slam, so I rank
1. 4♣ ART 2 places to play or slam-try.
2. 4♠ NAT Hoping that partner has 4+ ♠ or that the Moysian is playable, in spite of the pre-empt.
3. 5♦ NAT Also unilateral
4, 3♠ NAT Pusillanimous..
5. 4♦ NAT Ditto.
