I would kindly disagree. I'm looking at a project where HOT updates
are going to be a real performance enhancement, but I'll have to
create a hundred or so tables ALL with fillfactor tacked on the end.

Imagine dumping a db, setting the new target DB to default fill
factors and then reloading all the data from the dump. No need to
edit the dump file or a schema dump etc... I could definitely see a
lot of use cases for a default fill factor.
