I have an aggregating processor that generates code from other annotated generated code. In the initial round, there won't be any generated annotated elements to read from, so I defer the aggregated symbol. In subsequent rounds, I get the generated values.

One thing that occurred to me in this is that there's a risk that I may infinite loop if I keep deferring, but KSP guards this by just finishing if a round didn't generate anything. Wanted to confirm that's the case!

Similarly - curious if there's a better pattern for a case like this where we want to aggregate all generated types with a given annotation, and not just partial slices each round. i.e. worried about generating multiple times when I only want to generate once with all aggregated types at the end.

Example of what I'm doing: https://github.com/slackhq/circuit/pull/1197

Hmm, it seems in some cases it gets racy and results in rounds where both no files are generated but also none are picked up by our processor, resulting in KSP to throw an error 🤔
