Put another way, why provide a way to dump fuel when you can just run it
through the engines.

They didn't need to lose weight that fast, they didn't need to land 'right
now'. The fact that they flew around in circles for three hours was probably
a good thing, time to examine every possibility and double check everything
before landing.

As to why no provision for fuel dump, I suspect it is a cost driver:

Of course, everything is a cost driver. Whether or not to have carpet
is a cost decision. The real question is what the benefit side looked
like in their cost/benefit talks.
