I too am in favour of keeping the interfaces simple but there is a
subtle point about function in question. In the context of possible
multiple version support, there may be several bundles with the same
uniqueId but different version numbers. One idea was that the
framework would reconcile the view point of each bundle such that it
"sees" at most one version of the bundles with any given unique-id.
Header lookup is not equivalent in this case.

Subject: Re: [equinox-dev] BundleContext and getName
Actually Peter, the discussion was about getting a bundle from the
location, not the name. They slipped another identifier in. Rather than
proliferating methods I would encourage using Bundle.getHeaders() to get
information about a specific bundle. If you want to add something to
BundleContext, it would seem much better to do
BundleContext.getBundles(Filter filter), where you can search on any of
the header fields. That way when you find out that you want to look up a
bundle by another manifest property (potentially Eclipse specific) you
don't have to add another method.
