They have definitely scaled back. Since you have a few particular items, it'd be best to ask if any of those are available.
While not exactly what you're looking for, I do have some Ngara acei and L. sp. mbamba, which are sort of similar to the acei and hongi on your list. I've been growing out a group of each and was going to keep a few for my mbuna display tank, but will have extras of each, in both sexes.
