I might want to put a colon prefix on a tag that is not (and will
never be) associated with a namespace, for instance. More commonly,
it's not uncommon to want to omit a NS declaration in an output
file because it's to be an external entity body that be included in
another parsing context at a later time, and in which that namespace
prefix will be properly bound.

I'm outputting some other data format, but I want to embed a little
piece of XML in the middle. The other data might establish a
"namespace" binding in some other syntax. Or I might, as discussed
above, be using colon prefixes to mean something else.
I might be needing to force colon prefixes to change in some odd way
to accomodate a DTD that I want to conform to. Since DTDs don't know
about the "semantics" of namespaces, that requires syntactic control
over the prefixes. There's surely an annotation that could be added
to a system like the one you want to ask for particular prefixes in
particular places, but that starts to be a lot of complication to
prevent a pretty easy to avoid error.
It's a tradeoff of flexibility versus automation of error prevention.
