   The [answer to feedback 
1](https://github.com/apache/maven-compiler-plugin/pull/1144#pullrequestreview-5406649762)
 seems strange (maybe it was generated by AI)? Dependency tracking never 
existed before this pull request. We only had a direct, one-to-one, 
relationship between modified files (as detected by timestamp) and recompiled 
files. We could very well add dependency graph without ABI. They are two 
orthogonal axes:
   
   * Dependency graph replaces the _one-to-one_ relationship between modified 
files and recompiled files by a _one-to-many_ relationship, but the modified 
files can still be detected by timestamp.
   * ABI replaces "modified files" by "_effectively_ modified files" (from the 
point of view of a consumer of the API).
   
   Committing the two concepts in two steps would make the reviews easier. For 
example, one thing that I would like to check is whether the 
`.abi-incremental-state` file created by this pull request could be merged with 
the existing file generated by the current version based on timestamps.
