You are right, working with POJOs and Case classes does not always give you
best performance but limiting the number of supported types results in bad user
experience. Types that are supported in general, should also be supported by
features. Why can't we use POJOs in SQL? Is `f4 IN (f3, f2, f0)` not possible?
