This means that ssh's default cipher will no longer profit from
hifn(4) or glxsb(4) acceleration.

People relying on such hardware acceleration will have to weigh
that benefit against the risk associated with using AES-CBC:

In the absence of hardware acceleration, AES-CTR and AES-CBC perform
the same.
