This is FUD. Hans do you have figures on how many fixes for R3 have

Just because you do not see how to use a new feature does not mean its useless...

When you are exploring new stuff its almost impossible to see the best way to
do things. Once R4 (and other FSes) use these new features (or not) it will become more
obvious how they should be coded. As it is not its a bit like trying to decide your
new baby will be a doctor when he/she grows up - its not something you can
predict.

And so is R3 - just no new features are being added...

See above - this should presend NO problems.
