That's not something to be proud of, that's something you are supposed to do in the first place, i.e. it is a reason to be ashamed of if you don't do it.
Stable and well implemented? We already had it in WindowMaker 10 years ago, and in fvwm for even longer.
Heck, you could abend wmaker and it would restart without any major loss of state (and no data loss)... so even if you did manage to make it segfault, it would not cause you trouble.
