@haarchri - Nice work, thank you for the PR!

I've asked for one update to improve conformance compatibility. This works well in a local test.

[haarchri]

@AaronME changed the example, squashed commits & rebase master
thanks for review ;)

[tilegg]

What is the status of this feature?
We were hoping to get this as part of the upcoming 0.20 release. Is there anything blocking or can we expect it as part of the release?

@haarchri This looks great! Thank you for the contribution.

I was able to create and delete the examples with this code.
