As a senior engineer I completely agree with this. A few days/week remote is fine. But full time remote is a disaster for junior engineers.
As you alluded to, it's not just easier access to senior engineers. It's also feeling like you're part of something that matters. I've been lucky to have those kinds of jobs in the past. Now I just have a job, I'm fully remote, and I hate it. It would be even worse if I was just starting out.
I suspect that some companies will eventually migrate back to a hybrid model because of this. I can't be the only senior engineer who feels this way.
