I remember when Mandrake was a young distro – a redhat derivative – and they (gasp) chose to compile for i586 instead of i386. People were like VROooooOM! And a bunch of other people were like: why would you target CPU instructions that not everyone has?!
So these are only the times they get caught.
Likely placeholder art making it into production because no one is checking, rather than a deliberate policy. But still bad form.
