I don't know why are we copying memory in the first place to just read a vector.

Probably for explicit ownership of the underlying buffers otherwise maybe the contents change between when it's sent back vs when it's actually read?

@hashhar this is read only memory. I don't think this is the reason

And we seems to do it only for lists, but not for other types and it doesn't make sense because they are encoded in the similiar way

I think that we were using much more memory than needed
