I think the feature we all want in light of this is a simple backup+restore which uses a users SSHD server somewhere so you can wipe completely before travelling and then restore completely when safe again.
Would obviously want it to also backup/restore esim's...
I'll take a complicated backup+restore. I haven't been able to back up my apps since I had a Nexus.
Actually the main thing I want is to be able to use my phone however I like, and install whatever I want, without Google telling me whether I have their permission to do so or not.
