It's not because of any signal here... It's most likely just practicality and being used to deal with other cryptos, where "you effectively only have 1 key, which is the seed key". So, likely the additional research for understanding more about Hive security has not yet taken place. Having that said, it's worth taking time to teach these integrators as it will change the perspective of how the crypto world needs/risks are with the amazing use cases Hive already has.
These are golden opportunities to embrace teaching... which will value everyone on crypto, not just Hive (or the integrator).
But for purposes of testing, one can just create (for now) a new account and be sure there is little risk involved.
