It goes of course even more for libraries above that level. I don't see any
future for code sharing (rtl,libs) between bytecode and native. I've seen
the mess with Delphi.NET on the delphi side, and don't want a slippery slope
in that direction.

The pointers are just the first thing. Object model, RTTI etc are next.

But if the overlap with the bytecode generator is only in the compiler, then
that satisfies me, and is it something for the compiler devels to decide.
