We can also remove some hacks we have used in the past.

feat(library/tactic): 'exact' tactic report unsolved placeholders in nested expression

Actually, the elaborator is the one reporting the unassigned
placeholders. The 'exact' tactic just makes the request.
To implement this feature we had to extend the elaboration interface
expected by the tactic framework.
