oh I didn't see this:

Note 1: now it does not work, functions from the parent class are not generated or exported.

NearBindgen doesn't walk through parent class, it may be possible to identify extends pattern in our babel pass then recursively NearBindgen on parent class

Yes, it should be possible (not tested), the question is - is it the best approach? I will experiment with this.

const ali = await root.createSubAccount("ali");
