It does not appear that additional restrictions on who may request a 2-byte ASN are necessary at this time.  If at some point 5+ years down the road the rate of 2-byte ASN demand starts to exceed the recovered supply and the 2-byte ASN inventory is depleted, we can consider a waiting list and/or technical requirements for requesting a 2-byte ASN at that time.

It was unclear if the present 2-byte AS number inventory would last sufficiently
long (i.e. past the point of operational impact) to avoid the need for a wait-list.

Having now reviewed the data, the need for wait-list is at present trajectory is
likely 5 years out.  It is up to the community whether it is worth working now to
address the potential situation that may occur at that time.
