If Signal can securely store a backup on their cloud, Signal can securely store a blob on my phone. A blob that should just copy along with the rest of my data when I upgrade phones. Any data security paranoia with regards to the on-phone blob applies equally to this cloud backup. Any data security paranoia can be mitigated by applying the paranoia safeguards to the key material securing the blob instead of to the blob itself.
I'm baffled by Signal's continued insistence on their cumbersome, user hostile, and backwards data migration process. It's dumb and it's likely the biggest hurdle blocking most people from using Signal. Most people will not realize at first that Signal's data doesn't transfer when upgrading a phone until it is too late and the data is lost. Losing data is inexcusable. The separate data transfer hassle is unnecessarily painful and a reminder to look elsewhere.
