This is usually done at the gerber level, not at the pcb level. If
you're making these changes in pcb, just add or remove the trace :-)

What I really want for solder jumpers is the ability to (un)mask them
for solder mask, (un)mask paste mask, and metal short options.
that is to disable them from production and we know that they are
going to be open, put solder mask over them to prevent accidental
shorting.

Those look like they might also make good switch contacts for
elastomeric buttons / keypads.

I did a couple of jumpers that I believe are similar in size to the
ones I had seen on an Arduino board. There is jumper and a
two-way jumper. Pic attached.

Your solder jumpers are starting to look like PCB inductors:

It's more like they're unsupported, not "forbidden". Nobody's added
them yet. Plus you get interesting questions like "where to rat lines
connect on them?"

Check with your CM about how they handle non-component
solder. A "part" like this might require a special setup operation
on the Pick&Place machine, or worse require hand assembly.

Looks reliable. Why are copper arcs forbidden in elements? Does this
mean I can't have a footprint that looks like this?

I like this and hearby request that you update the fileformat to support it as
an element. :P

The footprint in the lower right
jcl,
I have made this the size of 0603 parts so that i can solder ball
them, or stuff them with an 0603 resistor.
Could we make a copper shorted version as well?
It allows for the reverse of the idea, by default it is connects two
nets that an exacto can cut out.

You can combine four rounded pads and a square one to form each half

You might look at JMP_SMD.fp in my section of gedasymbols. These jumpers

I was thinking of a range of gap sizes, so you could see how well they
bridge.

If you want a test board, I can probably etch one tomorrow and mail it
to you. Just send me a .pcb file. Or a postscript file, if you want
to try semicircles also.

The round pad with split "affords" bridging. Two square pads don't quite
have the same effect. Too bad PCB can't make the semi-circular pads!

I'm sure you have a reason for using special pads, but I'd just use some
SMT resistor footprint. I've made 3-pad strappin
In Eagle there are a couple of solder-jumper footprints. To jumper between pads
you create a solder bridge. The two pad jumper looks like two half
circles with a
gap in between. The three pad jumper consists of a half circle on each
end with a rectangular pad in between.
