Absolutely. Even publicly available data indicates that with old SWIPs.

One alternative to waiting until doom time that is within power of
ARIN public policy is to modify so that when somebody asks for new
IP space they have to be able to show not only is their last allocated
block 80% utilized but all other blocks in ARIN system as well
(including legacy blocks). This might cut down on the requests by
some large ISPs and force them to look at their existing ip space
(at the expense of ARIN personnel doing more work when looking at
IPv4 additional allocation requests).
