This came up in JDK 9 and the decision at the time was not to require jdk.zipfs as it's a service provider module. The addition of the source launcher, the addition of --enable-preview, and more use of --release N means more ct.sym usage. It probably isn't too interesting to have a small runtime image that contains jdk.compiler and not jdk.zipfs so Adam's proposal mightn't be too bad, it's just a bit weird and not something that we'd want other libraries in the eco system to do.
