- Can't have tags for the CloudFormation stack itself (needs to always use scripts)
- Add global template tags, which will be set on each taggable resource (i.e. company name, etc.)
- No tags on ElastiCache, CloudFront Distribution and maybe others
- Mappings should allow arbitrary levels (currently fixed to just 2)
- A mapping should be able to nest another mapping (via something like
{ "Mapping" : "..." }
)
