Important code, whether it is mission critical or not, should always be in active maintenance. Code which is no longer needed, can be junked, but if any code is still used, even if just once per year, it should be in the active maintenance pool and assigned to one or more coders to keep up to date.

You may have a small application and a large pool of developers with time on their hands but others do not. Time can be allocated to fix bugs and deal with changes in requirements as the costs for this time can reasonably be passed on to the customers, but taking time to make the code look pretty is time that cannot be charged to the customers, therefore cannot be justified.
