From the project README

An excerpt from the repository, fetched Nov 13, 2026.

Read the project’s introduction
People wishing to submit a BIP should first describe their idea to the bitcoindev@googlegroups.com mailing list to gather feedback on viability and community interest before working on a formal description. Please open a pull request to this repository only when substantial progress on the draft has been made, preferably when the draft is nearing completion. Authors do not assign a number to their own proposal. After a proposal meets the editorial criteria, a BIP Editor will assign a number to it and publish the proposal by merging the pull request to the repository. Please see BIP 3: Updated BIP Process for the full process. The BIPs repository serves as a publication medium and archive. Having a BIP published here indicates that the proposal is in scope and has met other formal criteria for this repository, but does not indicate that it is a good idea, has community consensus, or that it is about to be adopted. The BIP Editors are expected to be liberal with publishing BIPs and to try not to be too involved in decision-making on behalf of the community. Beyond the formal criteria, evaluation of the proposals is left to the audience of the repository. When a proposal is controversial and it cannot be agreed upon whether it should be published, the conservative option will always be preferred: the proposal will be closed. Those proposing and opposing changes should consider that ultimately acceptance and adoption rests with the Bitcoin users (see also: economic majority).

I agree with the point the author is making and generally am just as annoyed by arbitrary password rules; nevertheless: > chili dog monkey nutso Is definitely not 18 quintillion years at best it's approximately 250000^4 which is 2^72.

The issue has nothing to do with a particular transaction or block, it was going to fail anyway and just happened to be triggered by a large block.
