I really agree, especially with "There is no universal semantics that will deal with every case." When I enter a time for an appointment, then travel to a different TZ, but know I'll be home when the meeting occurs, I have to tolerate the Macintosh calendar converting my meeting to the local TZ, then back to my local TZ, which ends up being odd at least, and confusing and annoying when it first happened.
