Would you keep fixing the underlined spelling mistakes on your “watch out for holes in the pavement” sign while people are already walking there?

There are contexts where quick and dirty and (hopefully) come back later are warranted. Far more often it is just an excuse for shoddy work. You used the word “perfection” as the contrast to “technical debt”. Granted, technical debt is not a well defined term, but I am simply highlighting that “free from technical debt” in no way implies anything like perfect. It just implies well made.
