Personally I'd suggest a lot of testing first. Not sure if there are
any lingering stability issues, but as far as performance goes in
firefly you'll only likely see speed ups with very skewed hot/cold
distributions and potentially slow downs in the general case unless you
have an extremely fast network and cache tier.
In giant and master, there are a lot of improvements being made to
decrease unnecessary cache promotions and blocking.

Are cache tiers reliable in firefly if you *aren't* using erasure pools?
Secondary to that - do they give a big boost with regard to read/write
performance for VM images? any real world feedback?
