Simple example: feature X is rarely used (thus we should get rid of it)
Hold on, why is it rarely used?
Is it hard to use? Is it hard to find? Was it poorly named? Does it work right? Does it get me 80% of the way there? Does it get me 20% of the way there? Do I rarely need it but when I do need it it's a huge time saver? Am I hesitant to depend on it because I fear it will be taken away in a future update?
