No. its nothing to do with performance. It is about getting rid of

Well, if fixing it makes Cog slower, then it *is* about performance.
Just making everything uncompact without changing the image format
doesn't really buy us much: it would make Cog slower and the image
bigger with no benefit. The benefit comes from having a new image
format that is optimized for speed rather than space - getting rid of
compact classes would just be a side-effect of the new format.
I like this proposal, but wouldn't this have also an overhead? I mean, ok, we don't have to pay for the ifs to check whether a class is compact or not, but we are gonna to pay always the indirection (which right now is only for compact classes). You know much more than me so probably this overhead is smaller that today.
