Some things can be unchanging
Years I did some XSL transforms for processing some XML based climate data.
These (with a few tweaks added by others) became widely used and are essentially "complete".
They will only need changing if the format of the XML data to be processed ever changes
There is plenty of code that will only ever need changing if input data changes in some way (or, if the code is responsible for data output then if the required output format change, or data transfer method changes (as most things are a "file" in OS I mainly use then this data transfer method changes not typically a problem for underlying code but scripts that glue things together)
Biting the hand that feeds IT
