Not to propose that one format or the other is better, but. The Intl API does not guarantee particular formatting in response to particular options. There is no spec-level guarantee that "short" weekdays will be abbreviations or that those abbreviations will or will not use periods. You shouldn't rely on these particular formatting details, nor to some extent should you be requesting us to select/adopt particular formatting. This particular formatting decision is really more a function of the particular language/locale and its conventions. If you strongly think lack of periods is desirable, you probably should request the change from the CLDR people. http://cldr.unicode.org/ We'll adopt (in time) whatever they choose to specify. And I strongly doubt we'll deviate from whatever they've selected for this stuff.
Can we close this then?
