Yep, and as in all warfare its about being PRACTICAL all the way, using whatever tools one might know how to handle in the fight :-)
Sometimes I feel like not sharing anything about stuff like this since it always pulls in the theorists with their "perfect" level of doing things, not realizing that this invites SPOFs
In a real fight you have to expect some real damage, keeping that on an acceptable level so that you are in for the long haul is what is necessary to survive & WIN in the end :-)
And that is why I have spread my #Bitcoin across platforms and devices, I can accept a loss of maybe 5% worst case but NOT losing most due to thinking anything is perfect...
