A very probable step, but this does not address a few other shortcomings of the scheme. Without some serious work to maintain the database it will be full of faults and corrupted data in a few years. People make faults entering data when they registrate, people move, they forget to remove the registration number when passing on a drone or parts to someone else and so on. Someone said that to go searching for a needle in a haystack, you first have to pull together the haystack, and this register is one large haystack.I suspect they will push the registration compliance to the retail level, mandating that any retail source that sells a quad get the requisite info and fees at the time of sale (much like the sale of guns is done in some states).
This could as well be part of the motivation from the FAA. To get flying RC vehicles into designated operation zones. The pdf I linked previous could be interpreted that way. I did not see it as clear cut that an RC model operated from a designated model flying site have to be registrated as an UAS.Perhaps RC model fields can be designated as a zone in which unregistered craft can fly freely (still following the typical AMA restrictions), or perhaps the FAA will simply chose to ignore (turn a blind eye) RC models that fly under the traditional AMA limitations.
The Civil Aviation Authority, Norway, is as the European Civil Aviation Authority pushing new regulations on unmanned aerial vehicles. In Norway it do not look to bad, in practice if look like the regulations will be an tool to whack those that fly in the wrong places.
