Moving the cap to the grid versus the cathode of the follower is best, as you say. The complexity is the negative voltage supply. It also moves the amp from being cathode biased to fixed bias.
However, if you ever tried using a Mosfet with its own negative cathode supply direct coupled to the grids of an output tube you might rethink using a tube here. Mosfet source followers are the only good use of a Mosfet in a tube amp signal path, a lot easier to implement than a tube, last forever, and have control over almost ANY grid current that might be thrown at them,
