Basically I came to my usual conclusion that stoppers are for children.

I think it is wrong to use 3♠ as specifically "S stop, club doubt" and use it more generally as "doubt about NT" so you will bid 3S without a stop in either black suit or with a generally flimsy hand. With a stopper in one of them just bid 3NT; this gives less away and the opponents might not find the right lead anyway.

That's fine, but it's much more useful as we use it if you don't bid 3N in slammy auctions, partner will know to look at his clubs.

1H 2D
2H 3D

playing 2/1 seems normal to me even if 2H promised 6. It is still very likely we belong in diamonds if we have a slam. Over that I think south should bid 4C since he has a huge hand for diamonds. I do not think that that denies a spade control since 3S is an ambiguous bid, might just be trying for 3N etc which will muddy the waters greatly if partner doesn't bid 3N. North can then drive it.
