Actually, no, this is not really a regression.

It really is. Even though the old behaviour was a bug (raw packets
should not be changed), if there are real applications that depend on
that then we have to keep those applications working somehow.
To be honest, I fail to see why the old behaviour is a bug when sending
raw packets from user-space. If raw packets should not be changed, then
we need some way to specify what the checksum setting is to begin with,
otherwise, user-space has not enough control.
A socket option for new programs, and sysctl configurable defaults for raw sockets
for old binary programs would be sufficient I think.
Thanks,
Ben
