Yes, if you don't trust the organization entitled to publish revised
versions to abide by its commitment to abide by a similar spirit, or
if that spirit does not reflect your intent as a copyright holder,
this are all rational reasons to remove the "or later", indeed (at
least as much as distrust can be regarded as rational, that is ;-)


However, as Ingo argued, not being able to patch holes, fix bugs and
add new features is a very bad idea.  He was talking about the
software, but this is as true when it comes to the license.

There are smarter ways of retaining control over licensing terms that
don't paint yourself into a corner that's nearly impossible to get out
of.

For example, the license provisions could state "or any later version
that CONDITION", where CONDITION reflects your intent as a copyright
holder, or it could state "or any other license that CONDITION."

They could also appoint a committee, or rules for formation of a
committee, to make this sort of decisions on behalf of all the
copyright holders involved.

Of course, since these are in fact all additional permissions, anyone
could take them out, or rather elect not to offer this option for
their own contributions (and then you might end up refraining from
merging them).

The mechanics are no different from "or any later version" provisions,
really, except that then you establish what the goals of your
community are without blocking upgrades that wouldn't conflict, but
that would rather further the interests of your own community.
