For users who in previous versions have relied on our lack of checking for whether variables are declared, they may previously have seen an overwhelming number of warnings when running Terraform v0.12. Here we cap that number at three specific warnings and then one general warning, so we can still give a specific source location for the first couple (for users who have genuinely made a typo) but summarize away a large number for those who are seeing this because they've not yet migrated to using environment variables.
