Note:

Browser support:

• Only Chrome (and Edge) implements it.
• Firefox doesn't support it, but its position is positive CHIPS (Cookies Having Independent Partitioned State) mozilla/standards-positions#678
• Safari doesn't support it, but the position seems positive now? CHIPS (Cookies Having Independent Partitioned State) WebKit/standards-positions#50

Library support:

• Go supports it golang/go@2bf686d
• Fastify supports it with warning about possible future change fastify/fastify-cookie@9e4652f
• python is planning the addition in 3.13 Support for Partitioned cookies attribute python/cpython#112713

I think it's probably fine to add this now.

Does anyone have any opinion on this?
