Of course that is the idea behind it.
The difference between a license allowing relicenscing under a newer
version of the same license and the case where you allow redistribution
under similar licenses is implied trust to an organisation or person.
1. Case with newer versions allowed implies:
- I once and forever herby trust the authors / maintainers (and
whoever they will be in the future) of this license.
- I ultimately agree with their decisions
2. Case where i allow redistribution under "compatible" licenses:
- I recognize that relicensing might be a reasonable action to take
place in the future and therby allow it as long as the idea of the
current license is not violated.
- If you really want to be sure, you have to ask me for permission
and that is because i refuse to agree with anything that will turn
up in the future without having seen it and decided about my
Practically, the problem is whom you trust. In the first case, you
accept the risc of giving ultimate trust to someone you don't even know.
This probably eases the case of relicensing on the user's side.
On the other hand, if the license requires derivative work to be
released under the same license terms, you require the "derivator" to
also put ultimate trust into that same third party.
In the second case, you trust only yourself ultimately and put the
burdon on the user to decide wether he trusts you and your intentions
enough to relicense under a newer version of the license without asking.
If you fear that you get too many relicensing requests, you could still
publish a note in a publically accessible place that you consider
relicensing under licences x, y and z appropriate and allow it without
explicite request from the time of writing on.
Actually, these strategies have also a lot of influence on how
information flows. In case (1) people check a central authoritative side
and decide about what to do. In case (2) someone might ask you for
approval of a new license and you might benifit by realising that a
problem exists while you might have overlooked it in case (1) because of

AFAIK, No. (unless not including such a clause counts ;)
That is exactly why i do not like such licenses very much. I prefer to
know exactly what license i use und replace it "the hard way" if it really
becommes necessary. Maybe i'm a bit paranoid, but people change and i
don't put ultimate trust in someone (i do not even know) happily.

Well... point of view. The process is always replacing a license. Since
the GPL is compatible with itself via the "further versions" clause, it
boils down to the same problem IMHO.

FAIK. Yes, it is possible. What should prevent it from beeing legal? You
explicitly allowed it in you licence (2.0 in the example).
