HI Peter! Thank you for really quick feedback.
Looks like I've failed to express that, but the idea is to have generic XBlockTab living in edx platform (or in separate repo always installed with edx platform), so there would be exactly one XBlockTab (not one specific tab per XBlock). In such case the tab itself should not cause any import-export trouble. Contents of the tab could, but that's just the case with normal course content, so I believe the same approach should be taken here (unrecognized blocks ignored). I believe we can extend/improve it to actually fail import or notify user more aggressively if some XBlock is not available. And I've just looked into course Export XML - some work might be needed there, but nothing really problematic as far as I can tell. To sum up: with proper implementation from author perspective import-export should not change at all. From developer perspective, export format won't change too - but maybe a bit extended. Code to perform export and import might need some alterations too, but nothing really complex.
