Oh I think the technical argument makes sense, it's just that as a user, Signal is pretty different -- it's mobile first, using the desktop version requires having the mobile app (and account tied to mobile). It's a lot different than say ICQ in the 90s where the account is with the desktop client. Additionally, I haven't tried it so I don't know how well file transfers on Signal work, but I assume it's not truly a first class citizen feature on it and if you start trying to send e.g. multi-GB files, I assume it starts to break down like most mobile IM where the intention is to only transfer small files (PDFs etc.) here and there.
