Aren't the hot compilers kept around under this mechanism to speed up the next incremental build round? I think it's not just caching of intermediate build output but also not letting the tools start from a cold start.

Yes, and I included that in my point. Certain compilers: Java, Swift, TypeScript are faster with long-running worker processes.

To be fair, that doesn't require a long-running Bazel process to manage them, but that does become a natural choice.
