An application we're building has ended up needing to implement a modified version of DefaultRoslynCompilationService to avoid caching of the list of compilation references. In the modified version we still depend (as far as I can see) on IRazorViewEngineFileProviderAccessor and ExpressionRewriter which are both in the .Internal-namespace.

Is there any chance this can be moved to the public namespace to minimize risks of breaking changes in the future?
