Incremental compilation good. If you want, freeze the initial incremental cache after a single fresh build to use for building/deploying updates, to mitigate the risk of intermediate states gradually corrupting the cache. Works great with docker: upon new compiler version or major website update, rebuild the layer with the incremental cache; otherwise just run from the snapshot and build newest website update version/state, and upload/deploy the resulting static binary. Just set so that mere code changes won't force rebuilding the layer that caches/materializes the fresh clean build's incremental compilation cache.
