Cross-repo PR attrition funnel, most PRs opened never merge

[ PLATFORM ENGINEERING ] [ MAINTENANCE ] [ TECH DEBT ]

The field guide to getting platform PRs merged

We spoke with 100+ platform, infra, DevEx, and AppSec teams about upgrades, migrations, and security fixes across dozens or thousands of repos. This is what we learned about creating the PRs, where they stall, and what actually gets them merged.
