Every single time I've tried to work on a file using tabs, I've had to configure my tabstop to be the same width the original author used in order to make the formatting reasonable. I understand that in theory customizable tabstops is preferable, but I've yet to see it work well.
(For what it's worth, I think that elastic tabstops, had they been the way tabs worked in text files to begin with, would have been far preferable.)
The user who submitted the report that Stenberg considered the "last straw" seems to have a history of getting bounty payouts; I have no idea how many of those were AI-assisted, but it's possible that by using an LLM to automate making reports, they're making some money despite having a low success rate.
