How you block some forms of tracking/ads is you inject your own STUB javascript functionality before the offending script loads.

executesitefunction.js could arguably be effected, but that relies on a site installing a particular function on window, which isn't required when using JS, and could be still done where the function is backed by WASM
A lot of stubs, a lot of functionality to kill a script when tripping certain trigger action, or force some properties.
