I disagree--I firmly believe that this is a good thing.

If Foo Corp intentionally/accidentally violates the GPLv2 on software owned by CA/Cisco/HPE/Microsoft/SAP/SUSE, but decides to do the right thing/come clean and release the code...

without this (plain GPLv2): Their license to the GPLv2 was revoked, is still revoked, and are liable to each of the owners. Even if one owner reinstates the license, the others don't have to.

with this (GPLv2 with GPLv3-cure): Their license is provisionally reinstated upon coming in to compliance, and permanently reinstated 60 days later if none of the copyright holders object.

With the plain GPLv2 it was worth it to play chicken. Now, it no longer is.
