Hi,
Thank you for reaching out to Google Ads API Forum.
Please note that Google Ads API only mirrors the behavior of Google Ads UI. If the values in Google Ads UI codes like locales and geo target constants are changed, then the Google Ads API will also mirror the behavior of the UI.
That said, it seems like your concern is more on the behavior of Google Ads as a product. Hence, I recommend reaching out to the Google Ads product support team (https://support.google.com/google-ads/gethelp) for further insights on your inquiry if these codes are changing regularly.
Let us know if you have further questions.
