Re: css3-fonts: should not dictate usage policy with respect to origin

Hi Vladimir,

Nice to hear from you as it's been some years since we spoke.

Regarding your parallel, I think you would agree that Web content authors
use optional APIs all the time, and do so effectively, e.g., see

I'm reminded of a different analogy, namely the pirating of videos in Asia.
A few years back, I heard (an unconfirmed rumor) that execs at certain movie
houses decided that if they couldn't beat them, then they might join them,
so they started doing early releases of watermarked, extremely low price
copies funneled into these pirate markets, which not only allowed them to
track pirate copying better, but also generated income. Now, I don't know if
this anecdote is true or not, but the point is that if some share of the
market supports a feature, then it is up to the authors to decide whether it
is worth their time and effort to use that feature, and for those segments
that do not support it, there are always other options.

I'm also reminded of various efforts to have UAs enforce HTML validity on
authors, which, as you know, has been universally rejected (ignored), and,
now we have HTML5 codifying how to interoperably process invalid and/or
non-well-formed HTML.

Eeven if the W3C writes a mandate for same origin or equivalent into UA
requirements, the W3C (and nobody else ASFAIK) certifies UAs as being
compliant or not. Without a certification process, such mandatory
requirements are almost worthless.

Best Regards,
