For each region code in ISO 3166-1, a parameter named independent is specified. CLDR should explicitly make support optional for those listed as no – especially for emoji IMEs that are used to select flags, just like it already does for deprecated codes. I would suggest to keep the independent states as regular and split off the rest as regions with the new status dependent.
The valid region sequences are specified by Unicode region subtags as defined in [CLDR], with idStatus="regular", "deprecated", or the "macroregion". However, for macroregions, only UN and EU are valid.
Deprecated region sequences should not be generated, but may be supported for backward compatibility.
Macroregion region sequences generally do not have official flags, with the exception of the UN and EU.
Some region sequences represent countries (as recognized by the United Nations, for example); others represent territories that are associated with a country. Such territories may have flags of their own, or may use the flag of the country with which they are associated. Depictions of images for flags may be subject to constraints by the administration of that region.
Caveats:
Although a pair of REGIONAL INDICATOR symbols is referred to as an emoji_flag_sequence, it really represents a specific region, not a specific flag for that region. The actual flag displayed for the pair may be different on different platforms, for example for territories which do not have an official flag. The displayed flag may change over time as regions change their flags and platforms update their software.
For some territories (especially those without separate official flags), the displayed flag may be the same as the flag for the country with which they are associated. For more about cases where characters have the same appearance, see UTR #36: Unicode Security Considerations [UTR36].
For additional information see the sub-section on Regional Indicator Symbols in Section 22.10 Enclosed and Square of [Unicode].

CLDR currently has 256 regular codes, ISO only 249 “officially assigned codes”. That’s because Unicode adds 6 exceptionally reserved ISO codes and 1 private-use code. At least the former group can be considered dependent as well.

For each region code in ISO 3166-1, a parameter named

Differences between ISO and CLDR
CLDR currently has 256
regularcodes, ISO only 249 “officially assigned codes”. That’s because Unicode adds 6 exceptionally reserved ISO codes and 1 private-use code. At least the former group can be considereddependentas well.
