I am not giving a conclusive answer, but providing the explanation of where this confusion comes from in my opinion.
I think the confusion begins with as follow:
- Section 22 (persons liable for registration) mentions some aspects of this 10L/20L/40L scenarios.
- Section 24 (compulsory registation) can over-ride Section 22 mentions Inter-state is compulsory.
- So this means, regardless whether you are not liable for registration under Section 22, if its Inter-State, you are required to register regardless of amount.
- Now the confusion starts as Section 23 also overrides Section 24.
- Now there was a notification that says the same you mention that if its 20L/10L, regardless of it being inter-state, registration is not required.

So, section 24 says that inter-state is required to register for GST, but the section 23 that overrides has a notification that says that 20L/10L special cases exists.
Moreover,
FAQ on cbic website contradicts this above notification by saying that if its inter-state, one has to do registration regardless.
And this is why GST registration should be done.

Additional details:
Moreover, the same FAQ mentions that if your work is
NIL-rated, you are not liable for GST registration.
So if your work in-fact is NIL rated, you are not liable.
However, as you export service and the way I know it, export of some services can be made 0 by LUT, does not mean the service itself is NIL-rated so do confirm with your CA.
This is also there is no problem with GST registration as you pay no tax, though compliance/filing is additional.
NOTE: Not a CA. Please do consult a professional/CA.
