Once again: what even is “cleanliness”? Are you writing it in lowercase on purpose, or are you unaware of methodologies that share the term? Or are you talking about Uncle Bob’s but refusing to capitalize?

“Clean” is a horrible qualifier for code. It is either too subjective/broad, or too loaded.

OK, I realized it was about something else. I don't follow Uncle Bob, and was referring to some people justifying "unclean"/incorrect shortcuts to gain performance.

I totally agree with you in that regard, "readable" and "performant" often go hand in hand. My gripe is with the "Clean" adjective, that often indicates code that actually isn't readable and is also low performant.
