I think this is OK in some situations and not OK in others.

To me it is a lot like writing in a human language. When I am texting someone I am close with there is no reason to avoid slang or to use the best grammar and punctuation. When I am writing my CV it would be advisable to be more formal.

The author of a dime-store novel will write at a different standard than the Encyclopedia Britannica.

My point is that you should write the code that is necessary for the situation and if you are part of an engineering organization the leadership or team as a whole should decide when to use what level of quality and should understand what the trade offs are. There are legit business reasons to write throwaway code when time is of the essence and there are times when you need to take the time to risk over-engineering/over-building something just to be as certain as possible that it won't fail.
