Why is `aws:autoscaling/group:Group` not in `_NOT_TAGGABLE_RESOURCE_TYPES`?

[agibralter]

Is there any reason not to include ASGs in _NOT_TAGGABLE_RESOURCE_TYPES? Right now it seems there's no way to avoid pulumi.log.warn(f"{args.type_} does not support auto-tagging") showing up when I run pulumi...?

It’s because technically ASG does support tagging, it just uses different format and, more importantly, an additional parameter than just a tag key and value (see https://www.pulumi.com/registry/packages/aws/api-docs/autoscaling/group/#grouptag). The warning just informs the user that the resource is not supported by the library as it would (as of now) have to somehow infer the value for the additional parameter which is required.

There are three options:

• Improve the warning to better describe what’s the issue. But this could get quite convoluted if there appear other resources with similar specialities.
• Handle this special case by adding some parameter to the registration function which would specify the behavior for the ASGs. But the drawback is the same as above. (CDK uses this approach as far as I can tell.)
• Leave it as is which I’d prefer.
