I sure like the idea of an ND filter BEHIND the lens so that one size fits all, but as far as I know, there is only the Fotodiox FE to EF adapter with the built-in variable ND filter. I'd love to see a variable ND filter that sits between a Sony FE lens and a Sony a7xx body.
Absolutely. A behind-the-lens variable ND is the ideal solution. Unfortunately it's not a practical physically-possible solution for native lenses.

You don't get the dreaded X problems? I got a variable ND for the 24-70, and the X skies are unusable.
Yes, the x can appear. That's why I referenced I can get about 5 stops of variance with the 18mm. But, in conjunction with SR app it's quite powerful.
You definitely have to take care and note the limitations. What I do is know the focal length limit in advance and count off the stops as I dial in the variance.
