When is it used?

[wes, 2015/08/14 01:13:32]

Solely in the extension server (get/set line messages, get resource content) and
related bits (ie, displaySearchResults delegate).

Then it should be at its call site since it discards the target and should be
caller's last resort. Hence does not belong to the mapping API.
