More than 1 million Bulgarian immigrants scattered across the globe are struggling to preserve their cultural identity/heritage and to pass it over to their children. There are Alexa skills (like "Bulgarian library" skill) which could help them teach BG-language to their children however currently Amazon does not allow access to this skill from anywhere except US,UK,CA,AU. Most of the world (Germany, France, Italy, Spain, etc) has no access to it. So, in this case splitting the globe into regions makes no sense whatsoever.

Would be greatly appreciated by thousands of people IF Amazon allows access to skills which are outside the physical "region" a given person currently resides into (without having to give up all other services tied to that region)

One way to accomplish this is:
As part of certification process, in "opt in for auto distribution" to have additional "exempt from local interaction-model requirement" checkbox along with "why you need this ?" text box where basically the developer could ask for a given skill to be distributed (say in Germany) even though only English interaction-model is implemented. This would be rare case anyway and Amazon still keeps the right to allow if reasonable or deny such request.

Thanks for consideration
