No it's not that annoying
The thing is that currently I use one power source - this is because i have limited space in the plane.
If I want to move the module to my second plane which has more space and I would use two power sources than I would need to brake (SJ2 and SJ3) the connection. Instead I could just remove the jumper.
Later if I would like to move to a smaller plane with limited space and use one power source than I would put the jumper.
This is just a proposal.....
