That doesn’t really work. The URL is an inherent part of the CC license. Archive.org might do link replacement but that does not change the license… it merely corrupts/misrepresents the license. Users of CC-licensed work are still bound by the actual text of the license. IIRC the URL was to refer to something that changes over time, thus making the license dynamic when archive.org works off of snapshots.
It depends on which license you look at. E.g. from https://creativecommons.org/licenses/by-sa/4.0/legalcode.txt:
It was a while since I looked at this but IIRC the BY license was fine in its early versions but none of the others were. Then I vaguely recall seeing links in later versions of the BY license as well (but that may have been hasty reading on my part since i’m not seeing it in the BY 4.0 ATM). Anyway, it’s a mess.
