The approach you outline is totally compatible with an additional one or two day time gate for the artifact mirrors that back prod builds. Deploy in locked-down non-prod environments with strong monitoring after the scans pass, wait a few days for prod, and publicly report whatever you find, and you're now "doing your part" in real-time while still accounting for the fallibility of your automated tools.

There's risk there of a monoculture categorically missing some threats if everyone is using the same scanners. But I still think that approach is basically pro-social even if it involves a "cooldown".
