'a pilot', re #19, it's the piloting skill which enables him/her to understand the quality of information and the circumstances (need) for use; not the perceived ability to use all available information.
Skill involves knowledge, such as how the wind speed display is calculated, it's accuracy, update rate, and relevance for flight condition.
Wind-shear during take off is best avoided with preflight assessment and planning; if a warning is encountered during takeoff then stick with the procedures - 'If ... Then', don't invent your own qualifiers, '... Except', (what is the action with a WS warning but no change in wind speed indication).
For every 'good idea' (opinion) the greater the opportunity for ill-considered 'bad' outcomes. Where is the line between stop and go for a 'slight wind change', is it chosen for each takeoff, what is it based on, what speed, ... each additional variable adds to the complexity of operation and the likelihood of misjudgement
