I could live with that.  I'm not sure if the key-values from v2 work
also with v3.  I did a brief test by copying some snippets from the
manual which worked, but maybe it was pure luck.  Do you know more?

It explicitly says that one has to use v2:

    When the physics package is loaded before siunitx, the command \qty
    is not defined: users will need to use the version 2 command \SI.

    When the units package is loaded before siunitx, the command \unit
    is not defined: users will need to use the version 2 command \si.

Maybe I'm misreading the above, but isn't that what siunitx is doing?

If the new key-values work with v2, I can add those old macros back to
siunitx.el and make a comment in the file.

Thanks for holding back my update frenzy :-)
