Pierre I tried to answer this post but found I could not without being a hypocrite.
On one hand you are 100% correct.
On the other hand I live in the real world and panel covers get removed all the time on live equipment.
The only answer I can come up with is that you must do what you feel is right, if that upsets ECs so be it.
I think it may affect your business, as in fewer calls.
Good Luck
