So, was this ever added to the spec?  I can't find it in css-text-3
or -4.  (I guess the keyword should be 'unsafe' now though)

https://drafts.csswg.org/css-text-3/#text-align-property
https://drafts.csswg.org/css-text-4/#alignment

FWIW, we have an implementation of this in Gecko (disabled by default).
We're (still) interested in having this feature added to the spec.

Thanks,
Mats
