Imagine I observe that my networks are getting more busy, and decide to invest some more in them. Do I (a) deploy a QoS management infrastructure or (b) use those same funds to pay for capacity upgrades? I think that most operators end up choosing (b) as it 'lifts all boats', whereas they are not confident that anyone will use (a) in the near future, and they know it won't benefit everyone (and in fact, will be to the detriment of some users who don't use it, and were previously doing 'fair competition' for bandwidth and now are 'second class' behind those with reserved bandwidth).
