Even if the impact for one tracepoint is low, if all tracepoints are enabled, eventually (considering that the number of tracepoints will increase) just the data flow to the trace file will start to slow down the guest. But I'm not completely opposed to removing 'disable' keyword, for example by turning all tracepoints off initially. Though then there would be no way to trace the initialization activities.
