Yes indeed. I find it utterly rediculous that there is a perception
that you constantly need to be patching a bit of software for it to
not be seen as abandoned. If a piece of software works and does what
it needs to do, why does it need to be continually patched? It makes
no sense to me.

I have my xf86-video-armada which I use on the Dove Cubox and iMX6
platforms. It does what I need it to, and I haven't updated the
userspace on these platforms for a while. Therefore, I've no reason
to patch that code, and no one has sent me patches. Does that mean
it's abandoned? Absolutely not.

Some people are just weird and think that unless stuff is constantly
worked on, no one cares about it.
