This also occurs if the script is destroyed. The code will continue to run even if the script is disabled or destroyed, which can leak memory or cause unintended behavior.
A case where I think I would run into problems with this is with client character ability code. Some of my abilities have infinite loops that raycast regularly or do other processing. If the character dies and I have one such script running in their character, the loop will never stop and rapidly start running duplicates as the player respawns (assuming the code doesn’t error out). This is extremely unexpected for me as a developer, and that I have to manually handle this is very unintuitive.
