How about a zero ohm resistor, either surface mount, thru-hole
or 0.1x0.1xX headers?

Every pin, even test points should be referenced in a netlist
and/or a schematic to provide closure for a complete route.
Hard to beat working with a schematic created netlist to
drive a layout rat's nest...somebody has to veriry proper
operation of the board and a schematic would greatly help
that person.

What is standard? Seems to be more of a function of the
tolerance to what PCB manufactures can handle. I think there
is a global set track width and a set track width per net
such as Power and ground.
