I think there are two paths forming in the "weighted controller" world.
1. There are actions and keyboards with the express intent of providing a piano-like experience. They are stage pianos, and then the whole world of digital console and "digital grand" pianos. Only the stage pianos have any real portability, and you can't get the very best actions in stage pianos or synths. They are reserved for consoles and "digital grands". As good as the MP11 is, Kawaii has even better actions in their console pianos.
2. There are "weighted actions" that offer more resistance and generally better feel than synth actions. There are plenty of musicians who need 88 keys to run samples, but who would not identify as pianists. There are pianists that would happily sacrifice feel to get something really light to gig with, and if they can be expressive enough for the band they are in... they will deal. Some want a compromise action that is also light enough to play synth or organ on. Nord makes these kinds of things - based on TP100.
If you need/want #1, there is nothing else going to satisfy.
If you want/can accept #2, the best actions are in the premium workstation boards: Kronos, Montage, Kurz Forte, etc. It is pretty rapidly downhill from there the more you want #1, but with other benefits.
Turns out the piano is a specific thing. It's keyboard is ideally suited for playing piano. But arguably, it is not superior for a lot of other things. So, we get a whole world of #2 that caters to all the needs other than "plays as close as possible to a piano". The marketing for a lot of #2 devices would tell you they are trying to make #1 happen, but its easy to spot. There are no really credible #1 instruments that are less than 40lbs. Some are much heavier. Anything that is 25-30lbs isn't #1.
That's my quick take
