agreeing with mark here, it's a topic that's popular enough that some
guidance and a spec would help.

fwiw, a while ago i started something myself but never got to creating a
first stable draft. here's a link to this abandoned effort:

https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fdret%2FI-D%2Ftree%2Fmaster%2FAbandoned%2Fidempotency-key&amp;data=04%7C01%7CDarrel.Miller%40microsoft.com%7Cd2c105f15362463502a908d92a4e79e4%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637587338855377376%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&amp;sdata=c9HB64yXulJX8PAMCWIggqEx%2BeKSft1gOOiz6RN2Qw4%3D&amp;reserved=0

maybe there's something useful in there, feel free to use in any way.

cheers,

dret.
