The "Parameter X not used" hint is specially annoying in the case you use many callback functions like the used in LCL (TNotifyEvent and alike).

Perhaps it's an idea to not show this hint by default for methods declared in the published section of a class ? Most likely they are callbacks.

Virtual methods could very probably join the dance ;-)

It would be good but i don't know if this is possible. In the Lazarus situation, the procedure (event) is added to the public section, so fpc can not know if is assigned to a published property or not.

The original idea was a local directive like {$PARAMETER_HINT +/-} or (a bit overkill/superfluous) {$IGNORE_PARAMETER [name of parameter]}

In my experience, those are less troublesome; callbacks are usually more generically designed (what the callee may possibly need). Nevertheless, that could work well, as well :-).
