The old WINGS program was simple and relatively dumb, and almost nobody used it.
The new WINGS program is fancy and complicated and fairly well conceived, and almost nobody uses it. The why is simple: getting flight instruction and attending WINGS-eligible seminars or online courses ain't cheap, and there's insufficient incentive for people to do it outside of their normal, every-day flying.
I get what they were trying to do, but the simple fact is that pilots who stay current will stay current, and pilots who can't afford to remain "properly" current (of whom there are many...) will just use a BFR. A BFR is as tailorable as a WINGS phase, anyway.
Good idea, poorly conceived, failed in the market.
