A reason not to have long refdes values is clutter. Names that are seven and
eight characters get difficult to place (legibly) on dense schematics and
PCBs. A seven character refdes will probably take up more board area than most
of you SMD components.

I usually use Jn for connectors. If I want to label a connector
"power" or "signal"
I will add labels to the schematic and PCB. It is usually easier to place two
smaller strings (neatly) than one large one.
