This is so much reaching for the stars. "VLS size"??? "Guidance"??? And what does any of this even have to do with a paved-over CV-16 and a completely not-designed-for-VLS CV-17? You consistently fail to account for the fact that CV-17 is clearly and obviously not even designed for VLS anywhere on its decks or its sponsons. There is no room for a VLS anywhere; the equivalent spaces on CV-16 that would have held VLS were quite literally deleted on CV-17 and replaced with additional flight deck space. They aren't waiting for a "compact MR SAM capability", or any MR SAM capability. This much should be quite obvious.Or, the HHQ-16 system they had prior was not considered practical for carriers (either due to VLS size or guidance or a combination of them or other factors), and they was a more compact MR SAM capability being developed that was appropriate for integration into a new class of ship being built but wasn't ready for 002 or Liaoning.
I see you chose to broaden the scope of discussion to "flattops" instead of LHDs. That is definitely a shifting of the goalposts, since neither the CdG nor the Hyuga conducts amphibious operations and VLS organic land attack wouldn't even remotely be considered in their mission profiles. Speaking of the Hyuga, I see you also failed to mention that the evolution of the Hyuga class to its larger descendant the Izumo class involved actually deleting the Mk 41 VLS and replacing it with SeaRAM.There are a small number of VLS equipped large deck flattops in the form of Hyuga, Charles De Gaulle and one of the San Giorgo ships, which are equipped with VLS.
For the Hyuga the Mk-41 VLS is loaded with ESSM and a VLA weapon; for CdG and San Giorgo the Sylver VLS is of course equipped with Aster.
As for "norm" -- I am talking not only about VLS on LHDs but rather giving large amphibious assault ships an organic long range land attack capability.
That is to say -- it is rather outside the norm for large amphibious assault ships to have their own organic land attack capability.
There is no way for amphibious assault ships to have a long range organic land attack without VLS. Or without fighters. Which, oh wait, US LHDs DO have. China will soon have a Wasp/America equivalent in the form of the 075, but it won't have the VTOL/STOVL fighter capabilities of these ships, which means it is in fact out of the norm for "large amphibious ships", but not in the way you claim. Fighters like the Harrier and F-35B can carry more ordinance and can strike land attacks far faster and more safely than attack helos, which is the reason they are carried in the first place. Where is the Chinese VTOL? Currently in the realm of speculation. Which I suppose makes it a near certainty? Regardless, the 075 without a VLS lacks a cheap and safe way to conduct land attack without a VLS packed with LACMs. I am also not convinced there is a VLS on the 075, but if there is one, it won't be packing MRSAMs and it won't be packing ASCMs, which means it will be packing LACMs (and ASW missiles, when assigned to such a mission).
