Should major version be increased every time a new rule is added?

Recently released version 3.1 is a minor update as it adds new features.
However new features means handling new rules, for example it now handle the new line at end of file rule.
This mean that if you are relying on dotnet format on your build pipeline, and some of your files are not following this previously ignored rule, on update your build will fail, which is a bit nasty especially if you build install the latest version of the tool.
So from a consumer point of you, this actually behave like a breaking change, so maybe it deserve a major version update.
Thoughts?
