"Depends" with non-existent module inside explicitly disabled "Product" is evaluated before Product's condition

I have Product {} with Depends

.

If Product's condition == true, QBS will die with error "dependency not found" during "resolve".
But if Product's condition == false (for example, we can pass command-line parameter) it will die too.
Tiny example: https://gist.github.com/nico-izo/8460cdbf6f0b729ea226

For now I think, that I should connect Product's condition with somethingNonExistent.present and use required:false property, but maybe QBS should not die on Depends fail in explicitly disabled Product?
