I strongly advise against quick reallocation of returned AS

substantial period of time.
The same should be true for other deactivated quantities such
as addresses, but that's a larger discussion.
Does another generalization of that principle explain why ICANN
has encouraged and enabled (or at least done nothing to
discourage) rapid turnover and reuse of domain names? If only
because of inherent slowness in RIR processes, returned AS
numbers and addresses do stay out of service for some period of
time (one can debate whether the time is sufficiently
"substantial") but, unlike domain names, they are not
reallocated in minutes after being released.
Given the use of domain names in locators and the risks of
someone picking up an undesired target if the ownership of the
domain name changes, wouldn't most of the same considerations
that apply to AS numbers and addresses at those layers of the
stack apply to DNS names at the application layer?
