XBEndpointRenderer adds response headers that sometimes exceed common server limits

This is why Drupal's AJAX response system puts this information in the response body, not the response header.

I think it'd be good to take a good hard look at why exactly we're not using core's AJAX response system and drupal_ajax wrapper format.

I suspect that reusing 99% of it and just introducing a new AJAX command (much like class OpenModalDialogCommand extends OpenDialogCommand) could be sufficient?

Needs a @traviscarden signoff because of the change to openapi.yml

Approved!

Clicked the merge because it looks like there's plenty of approvals there. 🚀

Is it possible that this didn't get merged in? I'm still seeing the large response headers on the 0.x branch, and it looks like MR 401 is still open.

Thanks q0rban, looks like the first merge failed because of e2e tests failing. Marking to needs work.

Thanks!
