1675752 - BCP 47 format for locales is not recognized on top-sites collection, Remote Settings Stage

Status: RESOLVED WONTFIX

(Firefox :: Top Sites, defect, P5)

Description

[Petruta Horea [:phorea]]

On Remote Settings STAGE, top-sites collection, the locales to be included/excluded are documented to use BCP47 format.
However, BCP 47 format is not recognized when setting some locales: for example RO locale, for which the BCP47 would be ro-RO, the localized Firefox build being branded ro. Additionally, seems that the locale field is also key sensitive, which would enable ro to work, but RO not to work.

It might be a common mistake setting wrong locale when attempting to exclude/include a locale.

Suggested severity: S3

While ro-RO is valid according to BCP 47, so is ro.

Afaik, we currently don't plan on using locale filtering. If we do at some point, it seems that we'll just have to know the exact locale strings being used in localized builds; it's not clear to me that something needs to change here.
