Simply making aircrews "aware" of their contrails status isn't mitigation. Knowing that you are leaving contrail doesn't tell you how long it will persist nor is there anything you can necessarily do about it...It could be a deep pocket of saturated air such that altering your altitude slightly isn't enough...and descending to lower alt to avoid contrails costs more $$ in fuel.
Nothing practical has been done because global coordination of any sort is extremely difficult:
Is there really 'no evidence' ?

Absence of action is not evident in itself of deliberate policy toward a the purposeful outcome of contrail persistence.
The second point is well taken though...here, I'll amend the statement:
Absence of action does not appear to me to be a manifestation of a deliberate policy decision to allow contrails to persist.
I do not see how a lack of coordination and consensus can then be construed as deliberate policy.
Conspiracism- think about it.
