Yes, I see those disclosures regularly even though I don't live in California.
Off the top of my head I also have California to thank for leading the way on:

- Clean, smoke-free air at work and in bars & restaurants
- Tanning booth restrictions for minors
- Single-use plastic bag bans
- Gay conversion therapy bans
California was also the first state to label Roundup as a known carcinogen. Years before the landmark cancer judgment against Monsanto. So it seems Cal/EPA knows what they're talking about and is providing valuable information not just to their constituents but to the rest of the country as well.
This comment was typed on a keyboard manufactured with chemicals known to the state of California to cause cancer.
While sitting in a chair manufactured with chemicals known to the state of California to cause cancer.
At a computer manufactured with chemicals known to the state of California to cause cancer.
And the cables supplying power to that computer were also manufactures with chemicals known to the state of California to cause cancer.
