Leaving the default to Any Inputs for expression analytics can cause some performance issue as a calculation could end up triggering multiple times per second if there are several inputs. Since this is the default, some users may not take the time to evaluate the performance impacts and will leave it to that default configuration. Users should be required to select the input(s) they want for triggering before being able to save the analytics, or at least be warned that Any Inputs could be too expensive.
