Hi, thank for reporting this proposal; anyway: it is not the first time I get this request.
openAIP is being produced only by openAIP and this converter was born with the main intention to convert from openAIP to OpenAir and not the opposite. If you want to provide some new airspace to openAIP just send them an OpenAir file: they are perfectly able to handle it properly. I'm personally contributing to update the Italian airspace on openAIP as well and we send the the updates also to them in OpenAir. By the way: they are also using this converter. They use mainly some GIS software and a git repository where the git commit IDs are used to identify airspace in their format; because I won't be able access that I won't be able to produce an openAIP file with matching IDs. And personally I don't like the fact that openAIP is listing all points point by point without using arc and circumferences definitions like in OpenAir.
Therefore, also because I don't have that much free time, it is not my intention to implement this feature in the near future.
Anyway this is an open source software: if someone will open a pull request with this feature implemented properly (skipping the IDs) I will be more than happy to merge it.
Best regards,
Al.
