The exact same wording would apply to the tab policy:

 "- but if everyone uses tabs, you don't even need to know that option
exists"

The other thing it does is introduce spurious differences between
revisions of the source text.  The source control system will duitifully
track & store all these spurious tabs -> spaces -> tabs changes, wasting
space, and making diff's harder to read since they're filled with
irrelevant gunk.  (Yes, I know, most every source control system worth
it's salt lets you compare revisions while ignoring whitespace - but if
everyone uses spaces, you don't even need to know that option exists).
