I fully agree and told that Karsten earlier already.
Another important reason is, that if we don't change the behavior of the
EM to always list locally available extensions, a lot of people that
want to use their own custom local extensions are forced to set the "Use
of unsupported extensions" flag and thus enable unsupported extensions
even from TER which they might not want, and which we don't want them to
do either, because if everyone sets that flag it would render the whole
supported/unsupported extensions idea useless.

I think this should be fixed before beta3.

cheers,
Ingmar
