memoryOptIn
fun memoryOptIn(activeProfiles: Collection<String>, devProfiles: Set<String>, bindHost: String?): String?
Why a node may fall back to memory when wow.backend is auto and no durable backend is available, or null when it may not: an active profile of devProfiles (wow.dev-profiles), or an internal port bound to bindHost, a loopback address, alone, the development exemption the host's safeguards share.
