No, the offerings are going away because
1. Disney seems to be selling nearly every CL room (except true suites) at a 40% discount these days,
2. Disney has tons of pencil pushers who just can't resist showing some kind of happy result from cost cutting (in order to ensure their own year-end bonuses),
3. Disney deluxes have convenience to the parks, meaning regular rooms don't have to compete with real rooms in the real world, and concierge/club level rooms don't have to compete with real concierge/club level rooms in the real world.
For a time, Disney was really pulling in the dough by offering club level rooms. The bit of wine and nibbles offered didn't cost nearly as much as the ridiculously high rack rates for club level rooms. Hence, club level was added to WL and BC and GF Sugar Loaf, even though those hotels/buildings originally were never designed with club level in mind.
No doubt club level is still a cash cow (amazing how many people will pay for the snoot factor of a gold card -- and I admit I'm among them), but the cash cow provides a lot less milk when nearly every room is sold for 40% off rack rate.
One of the worst things to happen to GF RPC was the decision to provide exactly the same offerings to Sugar Loaf that were being offered to GF RPC. This did not raise the level of the offerings in SL. No, it lowered and reduced the offerings in GF RPC.
A few extra visitors in a lounge is not causing the problem. No one eats that much -- plus, if one follows the Club Level thread, Disney seems to be changing Club Level food offerings, at BWI anyway, to things that are less appealing to most people and not appealing at all to teens and children!! At Innkeeper's Club, I asked why no muffins at breakfast. Answer: oh, we stopped offering them some time ago. Instead, there was an array every morning of dry (and no doubt cheap) pastries.
Club level has been a cash cow for WDW resorts and the cut backs (and the food/wine choices) are made in an effort to keep it that way, plus pencil pushers are determined to show real results for their cost cutting so their year-end bonuses keep coming.
