Get current locale by new Intl.Locale() without tag.

[WORMSS]

Is there any reason I need to do

new Intl.Locale(new Intl.DateTimeFormat().resolvedOptions().locale).weekInfo.firstDay

instead of just

new Intl.Locale().weekInfo.firstDay

to get the current locale?

How would you like to handle a situation where because of available data your datetimeformat resolved locale is different from your numberformat resolved locale?

This is requesting that new Intl.Locale() without a tag to return the DefaultLocale() . I think this is different from what this proposal intend to do - accessing information in a determined locale. Move to ECMA402 for discussion
