Motivation - let us have a macro with functionality, which have sense only if an appropriative compiler plugin is enabled.
Examples of use cases:

async macro can call direct-style methods marked by context parameters only if the appropriate compiler plugin is in the same run.
async macro can use the loom subsystem for transforming HO. method if target JVM is >= 21
macro can generate places for inserting instrumentation calls by instrumentation plugin if one is enabled.

Interested too. I am currently writing a macro that would only make sense is Capture Checking is activated.
