'really need it' is quite subjective. IIRC TypeInfo is mostly used for
GC, AA and sometimes arrays. You won't use most of this anyway and you
can still use a library template base Array/AA so this is easy to
avoid. TypeInfo is also required for type-safe runtime variadics.
Nobody uses these.

I think one place where you really need it is downcasting class objects.
But you only need a small subset of class TypeInfo for that.
