There is a lot of technical debt you can leave in the system without consequence.
Tech debt mainly becomes an issue when making changes to the code. If no changes are needed in the code and it is working correctly, it is best to leave the debt in there.
I think that gets to other people's points that if it doesn't have consequences it is isn't likely "tech debt". If you don't "owe" it to someone, and often that someone is "future you", then it isn't really tech debt, it was just a trade-off or a poor aesthetic. We have other fun names for ugly aesthetic choices that work and get the job done and aren't likely to be replaced such as "jerry-rigged" and "Rube Goldberg machine" and "duct-taped shambles".
