+              We marked it as "waiting for user interest" for now to gather some feedback from our community:
+
+              - If you would like to see this feature be implemented, please react to the description with an up-vote (:+1:).
+              - If you have a suggestion or want to point out some special cases that need to be considered, please leave a comment, so we are aware about them.
+
+              We would also like to hear about other community members' use cases for the feature to give us a better understanding of their potential implicit or explicit requirements.
+
+              We will start the implementation based on:
+
+              - the number of votes (:+1:) and comments
+              - the relevance for the ecosystem
+              - availability of alternatives and workarounds
+              - and the complexity of the requested feature
+
+              We do this because:
+
+              - There are plenty of languages/countries out there and we would like to ensure that every method can cover all or almost all of them.
+              - Every feature we add to faker has "costs" associated to it:
+                - initial costs: design, implementation, reviews, documentation
+                - running costs: awareness of the feature itself, more complex module structure, increased bundle size, more work during refactors
