A practical 1941 role for HMS Hermes

What could HMS Hermes realistically do in a combined Allied fleet by 1941?

Use her for convoy escort, where her limited carrier capability could still perform a useful escort-carrier role.

Hermes belongs on convoy escort rather than front-line fleet-carrier work. Her small air group and older design could still provide the functions expected of an escort carrier, making her useful without exposing her to missions beyond her combat value. The answer illustrates how an obsolete capital unit can remain worthwhile when matched to a narrower role.
