> Those are traditionally offered in Java in the form of bytecode transformation

And we've come full circle. I think they're traditionally written as bytecode transformations, because the entire pipeline for both writing and using many kinds of program transformations in bytecode is far simpler, more accessible, and more performant than implementing and executing a source-to-source compiler that feeds into another java compiler.

That said, there are also times you wish to perform transforms on programs for which you don't have access to source, in which case your hand is forced. Ideally, you would be able to write many classes of transforms agnostic to that context.
