Let us start by stressing that, of course, the maximal-update parametrization is definitely an intriguing recent development, and it would be very interesting to find tools to be able to understand the strongly-coupled regime in which it resides.
Now, it seems like there are two different issues tangled in this discussion: (i) is one parameterization "better" than another in practice?; and (ii) is our effective theory analysis useful in practically interesting regimes?
The first item is perhaps more an empirical question, whose answer will likely emerge in coming years. But, even if maximal-update parametrization turns out to be universally better for every task, its strongly-coupled nature makes it very difficult
Thank you for the discussion!
