Maybe. 

IMO semantically, you have new device, that should be configured
before use. It can appears after loading module. As for man 7 bootup,
there is no deps between early targets. So tmpfiles could start earlier
then zram device appears, and so on. I think separate service for device
configuration should be used anyway.

I should add RefuseManualStart=/RefuseManualStop= to unit
