What about 1♦-1N-2♠? Here more strains are possible, is it still better to play 2N as natural? And if you do, is 3♣ forcing?
Can't say for sure if it is better, but I still play 2NT natural here. For me 3C would be non-forcing.
Assuming 1NT denies as much as an invitational hand with 6 clubs, I don't think it is especially important to be able to distinguish between min and max 1NT responses that contain 6+ clubs. I would just bid 3C with most such hands regardless of whether I had 6 or 9 HCP and leave the rest (if there is a rest) up to partner.
We probably do not want to be going anywhere anyways unless partner has a club fit and/or extra HCP, especially considering there is a good chance that we have already wrong-sided 3NT. So I personally don't think it is a big deal that the non-forcing 3C rebid has a fairly wide range.
Another way to look at this: Do you really want to force to game just because you have (say) 8 HCP and a reasonable 6-card club suit? How well do you think game will play opposite some of the "light shape reverses" that have appeared in this thread?
Some maximum 1NTs with 6 clubs will be suitable for a (natural) 2NT rebid, a move toward a high-level diamond contract, or possibly a heart raise.
