The reality is that if you need more flexible working arrangements, you are extremely subject to the whims of people who want offices to be the primary mode of work. If they don't want you to be remote, they don't need venom or arguments or to seem angry or even to seem to have much of an opinion at all. Simple inaction and lack of effort, followed by an "oh I'm sorry I forgot to tell you after we all got back from lunch" 3 weeks later is enough to make the remote person's situation untenable. Eventually the "oh I forgot you worked here. Just kidding hah hah hah" jokes kick in and then you know you're a couple months from being let go.
To have a successful working relationship with people who aren't in the office, work must be done by the people who are in the office to keep things working. Essentially, it can't work unless everyone adopts a remote-first approach where major discussions happen in writing out in the open.
The massive proliferation of slack and similar in the covid era certainly has and will continue to help establish this mode of working, but the people who don't want it because they feel uncomfortable when they don't see butts in seats 8 hours a day will likely put in a lot of passive-aggressive effort to bring things back to the old status quo.
