I had been working to incorporate your suggestion regarding bl_len.
However, I have not had the time recently to finish that. I also need to
have another look at the size changes once that is implemented. I had
been hoping to use [1] to get some general size reductions on most
platforms, but I am going to have to revisit that as well. I would like
to work on this, but at the moment it's not high priority for me.
Changes like this should likely go in first, since I suspect it will
take another revision or two to finish up that series.
