I don't see what the issue is here, although the OP could have been more clear about their interest in this. Various solutions exist for all manner of problems - you pays your money and takes your choice.

It might be an idea to approach gland manufacturers as it would be nice to turn up on site and find these inside gland packs. Not easy to reach from the top of a gland plate into a pit beneath and these would make life considerably easier for anyone working on their own.

The earth connection is still relying on tightening a nut onto a plastic panel. As above, piranha nuts would be preferable.

Or two locknuts sandwiching the banjo.

Not really you got the earth tag on the outside with the bracket inside they do sandwich the plastic I agree but there is a fair bit of surface area of metal against plastic it tightens up with no problem.

Why has it got a banjo outside as well as a bolt through ?
I've never been a fan of drilling extra holes for no real benefit that I can think of.

One of the things I could see as being useful is an L shaped banjo that would allow an easy connection to it and also would help with locknut spinning.
