I recall some EPC suit saying that they would never sell a packaged
part.

At least, that's not much of a package. :-)

I once used one of their smaller parts 0.9 mm * 0.9 mm
in a chopper amplifier to take advantage of the small
charge injection. It turned out to be easily soldered.
They call that thingie a power transistor.

I used the Altium part decals that EPC proposed. They have the
solder mask on part of the pads. JLCPCB asked back if I really
wanted it that way. I said yes and it worked nicely.

I like the tiny 4-ball parts, like EPC2038. Their drain-gate
capacitance is about zero so you can do stuff that wouldn't work with
mosfets.

They recommend solder-mask-defined pads but that's not really
necessary; the worst aligned thing on a PCB is usually the mask.

'Sort of' responding to their sales team's feedback in Europe.

as long as alignment is good enough that the openings land on copper only the scale should matter
