Namely $redirect-rule working as redirect-if-blocked. uBlock Origin uses almost 600 of $redirect-rule while AdGuard 40+ if limited to Base filter. The main use of this are:

1. $script,redirect-rule=noopjs,domain=blog24.me (in Base filter): some websites frequently change domain or path to detect anti-block or ad-reinjection and in such cases this sort of rule is often used. If done by $redirect the rule breaks the sites as blocking all scripts.
2. /ads-prebid.js$script,redirect-rule=prebid-ads.js (in uBlock fitler): Some bait paths for anti-block/reinjection are used by many sites and in such cases this sort of rules are useful. It's possible to replace by $redirect; however, EasyList regularly removes rules used to detect blocker, then the rule become obsolete, or even worse can rather cause detection as the rule doesn't work on all sites. It's practically impossible for us to monitor all such changes.
