Thanks a lot @bpmckinnon! I actually tried to fix this years ago with our metadata implementation (linking just for future reference #744) but happy to accept this change instead.

Do you think you can sign off your commits and fill out the CLA?

I think you're right in that all that's left is the conversion_traits header (and it would be nice to have our own iostream/interprocess impl), we can look to solve that too.

I'm working on the CLA. I was doing this as part of work, so I'm looking for a corporate manager for the CLA.

No worries, keep us posted - we can contribute these changes on your behalf but would be nicer if you're able to get it signed

Alright, this should be ready to go
