Why to capture only for Index Insert/Update and not for Read; is it
because Read will be always fast ot implementation complexity?

Why not similar timings for heap?

Why can't we print when only Analyze is used with Explain, the
execution time is printed with Analyze option?

Could you please tell in what all kind of scenario's, do you expect it
to be useful?
One I could think is that if there are multiple indexes on a table and user
wants to find out if any particular index is consuming more time.
