First time for years (no salvaged one on hand) I replaced old with new but
had forgotten about those antistatic shorting links, wasting time trying to
find the short. Nothing on the box about the shorting link, only graphic
showing use antistatic wrist strap for assembly
Do they all have these solder-across semicircle land pairs?
This one Sanyo SF-P101 has them , so do KSS213 and K SM213, all ?
Is there something in the laser assembly that is especially prone to static
damage?

Yes, the laser diode. There's generally very little circuitry between the
cable and laser diode and it can be damaged by any number of things including
ESD.
