Isn't this a very common scenario, similar to what package management systems
call "optional dependencies"? 

I maintain a small podcast aggregator that tags podcasts using an external
tagging library as an optional dependency---people can choose not to install it
if they don't care about tags. That library is imported within a try/except
block.
