Each deprecation will be voted on individually, with the RFC needing to be finalized by July 13th. A notable debate emerges around whether proposals should include formal impact analyses. Juliette Reinders Folmer argues it is irresponsible to vote without impact data, while Tim Düsterhus counters that deprecations are not breaking changes and that impact analyses based on Packagist packages are inherently biased and incomplete. Rowan Tommins sides with Juliette, stating he will vote 'No' on any proposal lacking impact information. One concrete example shared is the 'return-in-finally' deprecation, where an analysis of ~5000 Composer packages found only 12 affected sites across 9 packages (0.18%), with 3 being actual latent bugs. ## Full article daily.dev links to this article rather than hosting it.
