Deduplication is explicitly called out as one of their efforts.

Duplicate bug reports is part of what people have been complaining about.

From a study I saw someone was able to reproduce about 40% of the bugs the top tier model Mythos had found, just by asking other models the equivalent of find me the bug in this file.

So unless everyone who has the resources to use these models to seriously hunt for bugs is in the consortium, it seems unreasonable to expect someone else will not find many of the bugs.

But perhaps this new effort will have enough of the people looking that it won't be a complete waste of time to coordinate disclosure.

If it works it will mean that bugs are patched before they are exploited. Which is good for people using the software. Recent history strongly suggests that can't be counted on.
