Thanks Nick for continuous caring on this. One thing we initially worry
is how to avoid duplicated reports to developer, like the one that can
be same as gcc's finding. We haven't found a way to effectively handle
this.

Do we mean the report with -Wimplicit-function-declaration can be duplicated
to gcc, so we can ignore them to avoid duplication to developer?

For the timeline, it's not decided due to the duplication concern. We tend
to look into next year after other priorities are solved for this year.
