Each deprecation will be voted on individually, with the RFC needing to be finalized by July 13th. A notable debate emerges around the lack of impact analysis for most proposals — Juliette Reinders Folmer calls it irresponsible, while Tim Düsterhus argues impact analyses are inherently biased since they can't capture positive ecosystem effects. Osama Aldemeery shares a concrete analysis for the 'return-in-finally' deprecation, finding it affects only 12 places across 9 Composer packages (~0.18%), with 3 being actual latent bugs. Rowan Tommins sides with Juliette, stating he'll vote 'No' on any proposal lacking impact information. The thread also touches on specific proposals like deprecating CURLOPT_PROGRESSFUNCTION, 'let' as an identifier, is_long(), and returning from finally blocks. ## Full article daily.dev links to this article rather than hosting it.
