The Indian government is extremely duplicitous when it comes to AADHAR. On the one hand they claim it is not mandatory (to comply with the supreme court judgement no this) but on the other hand they make it impossible to get by without AADHAR.
Even private institutions use this duplicity to force AADHAR on everyone.
Let's accept this, AADHAR is the most friction-less process to get things done. And Private Institutions aren't going to spend extra to satisfy some errant ideology.
There is nothing "friction-less" about Aadhar. Even with Aadhar you still have to submit a bunch of other documents for getting anything done - even for a bank KYC.
Also, different department in the the govt treat AADHAR very differently. The govt circular states that the Aadhar cannot be used as a proof of birth date or citizenship - however, the election commission uses Aadhar as the proof of date of birth!
Why didn't the govt simply issue a passport for people instead of issuing Aadhar cards? you need basically the same documents to apply for Aadhar as you would for applying for a passport - and the passport can be used for travel, as an ID proof, as a date of birth proof etc. So why have a separate process which duplicates all of this without any of the advantages?
Fro non-citizens, an equivalent residence permit with the aadhar number could have been issued.
The process for issuing passports already existed. So why recreate a completely new system?
Also, even with Aadhar, it has just become yet another entry you must mandatorily "link" to your accounts. you have to manually "link" your PAN to your bank account, your Aadhar to your bank account etc when the govt already knows which is your PAN and your AADHAR.
My take on it: I find it difficult to generalize the notion of layer removal when the bit depth of that layer goes to zero. It's wouldn't be straight forward although the authors provide equation 5. It feels like lot of information is missing in this work to even reproduce it. And authors do only 1 case study.
I believe some implementation is required to understand the authors completely. Example, optimizer modification for layer when it is removed in training.
