It could, but the heuristics seemed a bit brittle. To pick a few examples:

 1. elm-virtual-dom -> "elm/virtual-dom"
 2. elm-explorations-markdown -> "elm-explorations/markdown"
 2. elm-terezka-intervals -> "terezka/intervals"

We could add a special case for the "elm-explorations/*" namespace, but 
at least one of the others would need an explicit property. I *think* 
most of the packages in the "elm/*" namespace are single-element (e.g. 
"elm/html"), so maybe we could require the property for e.g. 
"elm/virtual-dom" and "elm/project-metadata-utils" ...
