API could - theorically you can use a flag in the session already....but you must not skip surefire is compiler execution is skipped. Surefire has its own inputs and even if the overlap with compiler can be important it is also far to be 1-1 so you skip surefire if nothing changed for surefire not a random other plugin (surefire can have custom paths, must consider the env, props etc...). A shared "did this artifact/folder changed" tool with a shared hash per execution can be a good way like in the build extension we have but no shortcut please until you do a new surefire which does not support all current use cases.
