Ok, this helps, I think. I'll give it a try.

In <https://issues.guix.gnu.org/47153#9> you argued---and convinced 
me---that we should keep the pre-built bootfiles in the origin until we 
actually don't need them. With 'chez-scheme-for-racket', that's already 
true, and there aren't bootfiles in that origin anyway. When someday we 
can actually bootstrap upstream Chez Scheme, presumably we'll add a 
snippet to delete the pre-built bootfiles from the origin, at which 
point the it will still be the same origin for both.
