It is mentioned in the 2002, I'm not sure if it is in an earlier version. 2002 is as far as I go back electronically.
1999

(2) Grounded Conductor. Where (1) an equipment
grounding conductor is not run with the supply to the build-
ing or structure, and (2) there are no continuous metallic
paths bonded to the grounding system in both buildings
or structures involved, and (3) ground-fault protection of
equipment has not been installed on the common ac service,
the grounded circuit conductor run with the supply to the
building or structure shall be connected to the building or
structure disconnecting means and to the grounding elec-
trode(s) and shall be used for grounding or bonding of equip-
ment, structures, or frames required to be grounded or bonded.
The paragraph has a vertical line to its left.
Changes in this 1999 edition of the National Electrical Code (as compared with the 1996 edition)
are indicated by vertical lines in the margin.

I do not know this to be a fact but I would still bet money that those restrictions are much newer then the allowance to use the neutral as the grounding means at remote structures and buildings.
My guess as well is those restrictions did not exist at some point. My best guess is about 1996 or 1999 is when it may have been added.
