I am afraid this output is not really good enough. From MI consumer standpoint, we need a clear
and concise labels for each resource type. Unfortunately, "shm" is not acceptable at all.
"Listing of all shared-memory regions" is unacceptably long. Besides, this would make a good title
for a table with output, but not really good title for a menu used to specify what to show. For
the record, here's the labels I have to use in actual UI code:

    ResourceClassContributionItem_10=Shared memory regions
    ResourceClassContributionItem_14=Message queues
    ResourceClassContributionItem_16=Kernel modules
    ResourceClassContributionItem_2=Process groups

Could GDB be made to output such labels?

Thinking about this a bit, it would work to add a third column to the types listing, call it "Title", and define it as something like "short distinctive phrase using whole words" or something like that, and with a note in the manual that the title would ideally be phrased to be suitable for a menu of types. This lets it occupy a middle ground between the ultra-short string that is suitable for a subcommand in the CLI, and the fully description that is suitable to head up a listing of objects.

I'll work up a patch along these lines. In keeping with the apparent tradition of numbered columns in the listing of types :-), I'll supply titles as "col2".
