@aldeka Sort of. I think I've never seen a case where a feature was shelved because "we didn't know how to do it". But I've seen plenty of cases of: "Dunno how to fix it. Rewrite from scratch a different way?" "Dunno why it sometimes fails. Put it in a try/catch, retry a second time, and if it still fails, move on?" "Tests occasionally fail, but the thing seems to work? Solution: change the test." And of course "Bug would take X time fix. That's too much work, so guess it's going unfixed."
