I think this community ought to be made aware that there is a more fundamental issue at stake regarding chromospheric (and coronal) fine structure in general:
What is the relationship between the magnetic field and the plasma?

The Sun will eventually decide what is going on if we can get the right observational clues.
Perhaps the decadal survey will recognize the urgent need to measure magnetism throughout the solar atmosphere, since simulations cannot be expected to answer this question anytime soon.
