So is the license different for x86_64? Because those builds come with readline:
❯ R-4.1 -q -e 'extSoftVersion()[["readline"]]'
> extSoftVersion()[["readline"]]
[1] "5.2"

Whereas the arm64 build has:
❯ R-4.1-arm64 -q -e 'extSoftVersion()[["readline"]]'
> extSoftVersion()[["readline"]]
[1] "4.2 (EditLine wrapper)"
