Does anyone have any experience using zero-ohm resistors in an RF signal path to select antennas?

I've typically used RF switches for this purpose, but that's also when it was necessary to allow the antenna selection to be changed "in the field". But for cases where the antenna selection is a manufacture-time option, I'm considering simple zero-ohm resistors.

I highly recommend using a normal SMD 10pF to 100pF ceramic capacitor, depending on frequency. They’re already used on the board, and tend to be cheaper than zero-ohm resistors, as we buy them by the bazillion rather than the handful.
