Hi
There is no technical problem to enable caching of cached volume (aka convert
cache_cdata LV into another 'cached' volume.
And as long as there are not errors anywhere - it works.
Difficulty comes with solving error cases - and that's the main reason it's
not enable so far.
So I don't see big issue with enabling usage on 'user's own risk'.
