With this launch, the pre-existing Intl.Locale object will add 7 additional
functions

   -

   Add Intl.Locale.prototype.getCalendars ( )
   -

   Add Intl.Locale.prototype.getCollations ( )
   -

   Add Intl.Locale.prototype.getHourCycles ( )
   -

   Add Intl.Locale.prototype.getNumberingSystems ( )
   -

   Add Intl.Locale.prototype.getTimeZones ( )
   -

   Add Intl.Locale.prototype.getTextInfo ( )
   -

   Add Intl.Locale.prototype.getWeekInfo ( )


These functions are already available in Safari 17 (Released September 18,
2023 — Version 17 (19616.1.27))
"Updated Intl.Locale to replace info getters with individual get… methods.
(105570888)"  (see
https://developer.apple.com/documentation/safari-release-notes/safari-17-release-notes?language=_6
)

so it should have minimum compat risk of breaking existing sites
