Request availability of JUtils

Would it possible to expose some of the behavior in in the official API (under, as I understand) in a future release? There appears to be some very useful utility methods in here we would like to use rather than having to re-create ourselves in a custom plugin. The method superTypes(Symbol.TypeSymbol) is what we are trying to use ATM, but there appears to be lots of other goodies I expect we and others could use in the future.

Using current LTS version 8.9, with API version and java API version
