does it matter that you had to implement 12 fixups at various points

If you want to come back later during a git bisect and find out exactly when that bug that just took down your production application was introduced, then yes, absolutely. I'd rather look through 12 small commits than one monster one for that use case.

Look at it this way - a bisect cuts the search space in half with each progression, so you can double the number of commits being searched with the relatively minor cost of adding one more call to bisect when bughunting.

If you're tagging your milestones appropriately and otherwise practicing good repo hygiene, having n number of extra commits for any value of n is a feature, not a bug.
