First, OK, yes, fine.

Second, for the record, I am compromising and "Saying Yes" to what you
want to do, over what I think is a bad idea. We have had a mechanism to
allow for saving off registers early so we can make use of them a little
bit later as a "first class citizen" for 14 years come this July.
Bloblist is not unique or new. What you want to do instead will come
back to be a problem for some other valid use case later on and require
some further architecture work at that time (or be an "ugly workaround"
that we have to accept if we want that case to work).
