Offer recurring filters as declarative #1160
Description
Filters are used for many custom cleanup tasks, but some of those are recurring.
For example, parameter removal in href.
Studying the frequency of filters usage and the type of handling they do would provide us with ways to reduce their usage (which lowers maintenance costs) and enable more contribution to be done without JSON manipulation.
This could also lead to solving CVE NF-008.
