Just spitballing, but I take it you don't participate in many multi-TZ meetings.
1. That's a non problem. If you're in meetings 8h/day the last of your worries would be TZ. Plus, such a time zone difference already exists today between e.g. France and the UK, Portugal and Spain, or for that matter within the US and other countries, and even within US states themselves (see AZ).
2. No it doesn't. What's most problematic when setting appointments actually is when daylight savings changes times. During the switch your regularly scheduled meetings may get messed up, times that worked for an entire remote team might no longer work for a week or two, and mishaps on new meeting schedules are all over the place. See e.g. https://youtu.be/84aWtseb2-4?t=230 to get a sense of how nutty it can get.
3. 4. I'm failing to see how using daylight savings or not makes any difference.
