Every feature removed by Google will have to be maintained by the open source community instead. That's going to be a workload that I'm not sure who is going to pick up. After all Chromium right now is maintained by Google. There's some forks like degoogled chromium but they are mainly focused on removing features, not rebuilding ones that have been deprecated.

Brave is an option but I don't really like where they're heading with their crypto tokens.
