the File menu doesn't seem like a great location for this to start with
I disagree since that is the common location for Import menu items in other software and note that users do use it multiple times as a one-way sync option because we don't have bug 737804.
The following applications all have/had Import in the File menu
- Internet Explorer
- Keychain Acess
There is no other more consistent place for it. Placing it in the File menu was based on common patterns in other applications… placing it in the Help menu was not AFAICT.
Also note that this is already the number 1 way the import wizard is opened on macOS (by a long shot: 63%) in Firefox 73 and the number 2 way on Linux (33% of the time). Even with the menu bar hidden by default the wizard was opened from there 18% of the time.
