Well suppose that a developer writes code that depends on an external library.
The external library on their own machine is 4.5; so they know that 4.5 works.
But will 4.4 work? How about 4.0? Or 3.9? Or 2.2? Maybe it works on 3.8+
and 2.13+, but not 2.0-2.12 or 3.0-3.7.
I don’t think it’s fair to ask people submitting patches to do the work of
tracking down which exact versions actually work and which ones don’t actually
work; particularly because...

…of things like this.
