It depends on what one calls "permanent".
It was just about whether it's possible to write a tool to please
everybody. And I was thinking how to do that. I suggested to split
all connections into two categories: "permanent" (stored in confis,
i.e. "setup-and-forget") and "temporary" (not stored in configs, i.e.
"use-once-and-forget"). Maybe I chose ambiguous names for those
categories, feel free to suggest any better. :)
There're also two interface types: CLI and GUI.
So that would be 4 ways to make a connection:
1.a. Permanent-CLI (ifupdown or a shell-script)
1.b. Permanent-GUI (NetworkManager)
2.a. Temporary-CLI (shell)
2.b. Temporary-GUI (NetworkManager)
None of tools support all 4 points good enough _yet_, that's why none
of them suits everybody. What I was trying to say is that it's still
possible to extend any of them to "fit them all", somebody just need
to extend it to support all 4 kinds.
Such tool, if existed, should please everybody. :)

It does not matter how often you use it. It's just whether you store
it in configs (that's what I called "permanent") or not ("temporary").

Not currently, right. But if someone could extend some of them to
support these, why not? Imagine a GUI/TUI (winetricks-like) front-end
for ifupdown, that allows you to configure VPN with a few simple
dialogs and store basic configs in /etc. :) If only someone wrote it...
