It is, but there's another aspect besides convenience and ergonomics. You surely know better than me that privacy and security are non-binary, and everyone has their threat scenarios.

In some cases, an ability to have multiple independent accounts/identities (pseudonymity) would - unfortunately but practically - beat true cryptographic security that Signal offers. I mean, personally, I'm less concerned about platform (e.g. Wire or Whatsapp) or some government agency learning that I'm talking to my buddies at certain schedule, than mixing up my acquaintances from different groups together, having to maintain a single identity for them all. Some people I talked with didn't knew my name or phone number, and I would be uncomfortable if they would. For me, in my life I've said less things I wouldn't want governments to learn about, than times I've used a pseudonym/throwaway account to talk to people.
