Also, as long as legacy ip_tables/x_tables is still in the kernel, you
can still run your old userspace against that old implementation in the
kernel.

But without offloading, and the various other benefits which I have
tried to clearly explain to both you and Florian.

Which is actually the business model to get people *off* the old ABI in 
reasonable time.

Hosting companies can't change what customers run in their containers.

But if they are told that a kernel upgrade will get them offloading
and increase their performance termendously, then that gives them real
value.
