Well you will affect the streams since you have to grab the ruleset lock
for it to add and remove rules.
Anchors need to be setup as well during the same process so, yes, you will
pause the other streams.

By design that's correct, though if you can control the way you add the
rules you can just avoid the anchors and just add straight rules.
