There are only two real reasons to register a namespace. One is to reserve the namespace without having to ever upload a distribution to CPAN. Simply being the first to upload to a namespace performs a first-come registration (See 1). Note that either method of registering does not reserve the namespaces below it. So registering or uploading Foo, does not reserve Foo::Bar.

The only other reason to register a namespace is to be included in the topic list shown on the search.cpan.org homepage. But that list is barely useable and most people search nowadays and don't bother to browse.

I personally hate reserving without uploading. When I searched CPAN to see if a namespace was in use before I uploaded my own distribution, nothing showed up. But when I uploaded, mine was listed as unauthorized because somebody years ago had pre-registered it and never made use of it. The author also refused a request to assign it to me, claiming he one day plans to make use of it. There are many claimed, but unused namespaces like that.
