Important code needs love, it needs to be improved, made more robust, have security issues handled, consolidated if it starts to bloat, to be cleaned and kept legible even for whitespace so you or the next guy can easily see and continue to look after all the moving parts.

If it's important, it needs and deserves all those things; they are not "churn" but maintenance.

Important code needs to become stable so it can be improved instead of fighting constant degradation.

Churn kills important code, making it unfit for purpose.
