Old/stale bundles/chunks not being cleaned from build dirs for ionic 4/Angular


I’ve noticed plenty of repeated bundle/chunk files from subsequent builds like


it can be even over 20 x hundreds of chunks - then also there is 2-3 directories per platform which makes magnitude of 1GB of data in total. Also building non prod non release app makes all the files into the builded artifact. Also I haven’t seen any kind of clean task nor its mentioned anywhere in the docs.

I know this concerns Angular build process still I am confused how/when I should consider cleaning all the build folders.
