I still don't see why this should be implemented in scale. This is Substrate specific and not SCALE specific.

The short answer is that Encode::size_hint is toothless: it's a 'best-effort' thing with a useless default implementation. Still, we do have the need sometimes for a more realistic size hint, and that need is generalizable to all of SCALE, not just Substrate.

This is also "toothless" as what is the maximum size of a vec?
As already said in element, I don't see this in SCALE.

Not implemented for Vec 😁. I'll move this work to the substrate repo instead though.
