I asked them the exact same question a couple years ago, as well as when they were gonna start making them for centerfeed actions(they werent doing them yet, but it was in the process). I was told a LA model wasnt in the works at that time but that they would look into it. I gave them all the scenarios you have also said(no mid-priced good synthetic stocks available except for Choate,TONS of LA's out there waiting to be upgraded,etc). Still nothing.

They have even posted on this site about this subject, but never gave any reason as to why they think it wouldnt sell.
