No, it’s not. Consoles (and technology in general) historically trend cheaper over time. Demand lowers, manufacturing cost lowers, newer tech releases, costs adjust to accommodate.
It’s very abnormal that the current gen of consoles has not only not gotten cheaper yet, but has actually raisen in price. Like, very very abnormal.
Shrinkflation is a real thing, but historically it has nothing to do with consoles.

Agree, that’d be awesome. However, it’s probably not worth their time to create/maintain/support a self-hostable backup server/integration since this has been possible for many years now via Signal’s existing backup functionality. You can backup Signal to device storage, then sync that to a remote server using Syncthing or whatever else. Not super user friendly, but neither is hosting your own server.
EDIT: At least on Android
