I read this twice, and still don't know what this patch is trying to
accomplish. What problem does this solve, or what new feature does
this allow? I am missing a sentence or two explaining what the patch
does and why.

And you can probably trim the history part, e.g. I don't think it
matters much for understanding that it used to be called gummiboot, as
entertaining the name is.
