Well, those 20% cover 80% of interface usage. The most important where
interfaces are used is COM importing and that works usually ;)

No, but those are ancient. The problem is with extensions that they must be
maintained as every feature because they get broken from time to time. This is
simply experience or just follow up the online testsuite results. Though
everybody is careful with its patches, test results get worse if nothing is
done. So we're careful with adding new features.
