You have few comments to address in v9. I would say post v10 with all the
comments addressed without squashing. Give the clear instructions about
squashing.

Let the maintainer decide how they want to handle it. Pretty sure they
have seen these cases already. Worst case you may have to spin another
version. My 02 cents.
