List just all used services

This would be deadly useful for those of us who do pci compliance

That's actually a difficult question to answer sometimes - some API calls give you "AWS Managed" resources mixed in with your own resources. Currently, aws_list_all only has basic support to disentangle this (see https://github.com/JohannesEbke/aws_list_all/blob/master/aws_list_all/listing.py#L8 ), so you'd always get some results.

What you can do now: Just do query everything once on an empty account, and subsequently on a target account. The difference between (used services in empty account, used services in target account) will give you the definitely used services at least.

I'll leave this here as an improvement, as it may be useful. Maybe I can get a cached version of the empty account run into the package, so I can print out a listing like this...
