Lack of support for the refactoring using conditional expression transformation

[simpt5]

Tested tools and version:

Refactoring Aware Commit Review Chrome Extension (Version: 2.0.4).
RefactoringMiner (Version 3.0.4) maven dependency.

Description:

During the usage of RefactoringMiner, I found a refactoring case using conditional expression transformation that can’t be detected. Could it possibly be supported in the future maybe?

The following refactoring for conditional expression in the above commit can’t be detected.

The corresponding if statements are actually matched. I am not sure if this is a refactoring type.
It can be considered as Simplifying Boolean Expressions

[simpt5]

Yes, it is actually can be treated as a boolean expression transformation, which transform boolean expression using some rules without changing the program behaviors. It is indeed not a typical refactoring type as others. Since those transformations are based on rules and performed on the boolean expression, I am wondering if those could be detected (if it is worth to detect) using some strategies?

It is definitely possible to implement this in RefactoringMiner and get it reported with a new refactoring type Simplify Boolean Expression.
I can add it as a new feature request.
