Where do you find evidence to support the absurd conclusion that I would prefer to have policy problems hidden from me? I'll go through this again using small words: the policy is complex, the lint tool mumbles and the documentation is poorly organized. Your explanation about .pyc files makes sense and I would thank you for it if not for the tone of the rest of your post. I don't know why .py files should be executable. All I know is that lintian complains when mine aren't. Perhaps there is some arcane incantation I haven't mastered which makes that acceptable. And yes, I know there are reasons for the policy -- in fact I said exactly that the message you replied to. (Consider reading posts before you reply to them in the future.)
But having a reason is not the same as having a good reason. From the perspective of an outsider who just wants to create a policy compliant package the documentation, tools and (at least if you are a representative example) developers are decidedly unfriendly. In light of that the fact that packages created by people who aren't committed Debian developers are "policy-ignoring disasters" is no surprise.
