Just that specific scimitar.
"When you select this trait, choose one of the following benefits: proficiency with that specific weapon..."
Weird? Yes. "I know how to stab people with great-granddaddy's sword, but hand me a virtually identical sword that a smith just forged and I'm at a loss." But so it goes.

There's Arodenite Sword Training that grants you proficiency with the longsword.
You might also be able to talk your GM into bending the rules. When I run the Heirloom Weapon trait, I'm usually open to giving proficiency in that weapon in general, since there's already a trait that does that for longswords. But different people prefer different things.
