Question is, how are they going to identify tracking parameters in links ?
They can't just blanket remove all GET parameters (because it would break legitimate non-tracking links), plus advertisers could use subpaths instead of GET params for writing the tracking data.
Therefore I suspect it's only going to be arms race between a blacklisted list of GET params and advertisers changing up the variable names to escape it, making it unsafe to use any GET param at all because you can't be sure a link that works today will still work tomorrow if they changed their list of banned properties.
