We have multiple active proposals on this thread but it’s unclear which proposals "+1’s” should be attributed to.
From a threaded reading based on which messages reply to which: Alex’s reply with a +1 is to Benedict’s email and original proposal. Jon’s reply is to Blake’s email but says “to simple straightforward guidelines” (unclear if referring to Blake’s proposal or simple guidelines in general). Dinesh’s reply is to Jon’s, which carries ambiguous attribution to Blake’s proposal or simple guidelines. To keep our discussion tidy and positions clear, can I propose clearly attaching a +1 to a specific proposal or position in the thread so there’s no ambiguity as to what each of us support? – Scott > On Sep 26, 2026, at 9:32 AM, Dinesh Joshi <[email protected]> wrote: > > +1 > > On Sat, Sep 26, 2026 at 9:21 AM Jon Haddad <[email protected] > <mailto:[email protected]>> wrote: >> +1 to simple straightforward guidelines >> >> >> >> On Thu, Sep 24, 2026 at 1:01 PM Blake Eggleston <[email protected] >> <mailto:[email protected]>> wrote: >>> I propose the following guidelines: >>> >>> Contributors must have a comprehensive understanding of the patches they >>> contribute >>> Reviewers must have a comprehensive understanding of the patches they >>> approve >>> Reviewers must have experience with the affected systems commensurate with >>> the risk and complexity of the patch. >>> >>> This makes the expectations that have been mostly implicit explicit, >>> doesn’t gate keep on the contributor side, doesn’t tell people how to do >>> their work, and gives the subject matter expert, the reviewer, the latitude >>> to decide what standards make sense for the patch they’re reviewing. >>> >>> >>> On Thu, Sep 24, 2026, at 12:01 PM, Josh McKenzie wrote: >>>>> Apache Cassandra was fundamentally undeployable for four years between >>>>> Nov 2015 - 2019. >>>> CASSANDRA-8099 was a maximal manifestation of a specific approach to >>>> engineering and calendar constraints we've seen time and again on the >>>> project; I don't want us to conflate things here.

It encompasses architecture, harmony with the >>>>>>>>>>>> existing codebase, thinking ahead to future evolution of the >>>>>>>>>>>> project, and >>>>>>>>>>>> replicates context on the project as new code is committed.

There’s a bimodal >>>>>>>>>>>> tendency >>>>>>>>>>>> toward code that is entirely generated or entirely human-authored >>>>>>>>>>>> - but it >>>>>>>>>>>> is rare for someone to prepare an AI-authored patch to take an >>>>>>>>>>>> offramp and >>>>>>>>>>>> spend a significant amount of time refining the work by hand in an >>>>>>>>>>>> IDE. >>>>>>>>>>>> This hesitancy toward human participation in authorship of >>>>>>>>>>>> LLM-generated >>>>>>>>>>>> code is very concerning to me. >>>>>>>>>>>>>>>>> – Harmony with the existing codebase: Due to the >>>>>>>>>>>>>>>>> tunnel-vision of >>>>>>>>>>>> context windows, LLMs are generally unaware of conventions and >>>>>>>>>>>> norms >>>>>>>>>>>> present in codebases and very frequently reinvent concepts in a >>>>>>>>>>>> generation >>>>>>>>>>>> turn to suit a goal without view of the project’s overall >>>>>>>>>>>> architecture. >>>>>>>>>>>> This results in a profusion of messy and duplicated concepts that >>>>>>>>>>>> gradually >>>>>>>>>>>> sprawl about a codebase. >>>>>>>>>>>>>>>>> Again, none of these are grounds for prohibition of usage of >>>>>>>>>>>> language models in developing the project.
