But much better than the current behavior, where NetworkManager
remains disconnected. The small time when there is no connection
should not affect the system (a loss of connection can happen at
any time).

No, that's not the same thing. Connections marked as autoconnect
are automatically enabled even when the user hasn't requested the
connection explicitly, e.g. at boot time. Here this would be an
automatic reconnection, i.e. for a connection that hasn't been
disabled by the user.
