We’ve done this as well, and Arista support hasn’t hassled us about anything yet so I’ve been pleased. I’ve been very happy using Flexoptics transceivers in all kinds of equipment too, if anyone’s looking for something they know works, and you get a programmer that will let you code optics to certain vendors switches that don’t have unlock keys. It won’t work on all though, so investigate before investing if that’s a concern.

Yes, email support and ask for the unlock code, they will make you agree that you know that 3rd party optics may explode the switch and it's not their fault.
The command they give you will have a key/hash built into it (but will work on any switch) that ties the "unlock" to your org.
Ours looks like this:

Is there a way for unlocking off-brand transceivers usage on Arista switches?
I've got an Arista 7050QX switch with 4.14 EOS version. Then it has been found out that Arista switches seem to not have possibility to unlock off-brand xcievers usage (by some service command or so).
I've patched /usr/lib/python2.7/site-packages/XcvrAgent.py, made the checking function bypass the actual check and it helped: ports are not in errdisable state anymore. But despite of xceivers are detected correctly, links aren't coming up (they are in notconnect state).
If anyone possibly have does have a sacred knowledge of bringing off-branded transceivers to life on Arista switches, your help'd be very appreciated. Thanks.
