Would there be valid uses cases for us to support duplicate values ?

Without any feedback from OP I'll close this.

I could't reproduce the issue on Chrome but there seems to be an issue on Safari. Can you confirm that you were using Safari ?

@maximLyakhov Those are really straight forward to migrate to standalone. Why not migrate them directly ?

With the move to standalone and the amount it would require to support that, we dediced to not support nor plan to support this feature.

Since this is a `fetch` API only feature, I'd espect us to log a warning in devMode when using the `XhrBackend` (which is still the default backend at the time...

Can you make sure to drop that merge commit.

You'll probably have to update your main branch before rebasing to resolve that conflict.

Could you please amend the commit message and remove the breaking change mention. Our release note generation will pick up the deprecation notice even if it's not one.

We still need an additional reviewer to approve, my approval scope doesn't cover that the http module.
