Yes shame on you for not realizing a 0.x versioned technology would make breaking changes on minor version updates.

Given:

1) Terraform uses Semantic Versioning [0]

2) Semantic Versioning specifically states that 0.x APIs are not stable [1]

Therefore:

Your complaint that a 0.x versioned tool wasn't stable is not valid.

Conjecture:

Your complaint exists as an excuse to remain ignorant of a new tool or technology simply because it is new. This makes you a luddite. [2]
