> I can tweak my IDE to render a tab as however many spaces I like

Sure, IDE's are easy (though many people use multiple IDE's and/or editors across multiple machines).

I've also got a couple diff tools, a few VCS's, also the online parts of VCS like web-based pull request review UI's.

Tabs also tend not to play as nice with vertically aligned elements, if you prefer that for things like say the '.' on multi-line chained method calls, or longer function parameter lists.

I'm a tabs for indentation, spaces for alignment person myself. A multi-line statement should have the same number of tabs on each line. Any line after the first should then have spaces as needed.

I'll work without complaint or changing it with any existing code whether spaces or tabs. Mix the two for indentation however and fixing it is the first commit I make before touching anything else.
