Assuming "fixed rate" means "always filled to said rate" not
"fillable up to said rate"... then that makes every users node
look nicely busy. And if the rate is the same for all users, then
every user looks the same.

However all nodes in the net need to be always filled to
some rates. Otherwise adversary vampire can just watch
the nodes end user is connected to, or perturb the users
packet stream, or wait until user unluckily routes across
quiet middle nodes, etc.

If pad fill can be used to carry something, better than to
waste it.
