Thats definitely a good idea to look into such kind of cases (if it happens). I completely agree with you that we should first try to use the inbuilt features only whenever applicable. But at the same time it may depend on your requirement, objective, AUT etc.
as you said "wasting of 2 minutes in a hour writing code instead of using inbuilt features", would you like to elaborate the query specifying any particual instance when this happened at your side?
