The Prettier team has gone on to say they regret giving people several of the configuration options they did though and have a page dedicated to their option philosophy. https://prettier.io/docs/en/option-philosophy.html
Yes, you'll find no mention of regretting adding tab support to prettier on that page.
Key quote: --arrow-parens, --jsx-single-quote, --bracket-same-line and --no-bracket-spacing are not the type of options we’re happy to have.
That's because these are entirely stylistic choices. Tab support is a mechanical one. Worth mentioning as well that Prettier supports multiple languages and tab/spaces is a global option, whereas all of these are very language-specific.
