How much current can a nRF52840 GPIO sink before it's damaged? Will current limiting to 20mA be OK?

If you look at a person's Profile, the Nordic people seem to have a 'Nordic Support Engineers' and/or 'Nordic Blog Authors' badge on the right:
But I still agree that it should be plain in the post - one shouldn't have to go searching for it.
Hi,
See this answer. It was asked regarding nRF52832, but the spec of the nRF52840 is similar, and listed in the GPIO electrical specification. A single pin sinking 20 mA is OK.

But it's still missing the Absolute Maximum specification.
Also missing the maximum total limit for the whole chip - which is mentioned in the linked threads from 2 & 3 years ago, and also came up again just this month:
Hi,
Thanks, I appreciate you bringing this to our attention. I can very much understand anyone who might feel that this is sparsely documented. It has been reported, and we are looking into it. For now, this is what we have though.
Best regards,
Andreas
