'Nobody' is too strong (done it a few times) but yes, it's not a common operation.

But the point is that alists has several more advantages: counting number of keys is twice as fast, iterating and/or transform the collection easily done with mapcar, mapcan, dolist, mapc etc. Plists have no real advantage from their structure.
