I think this change is well supported by the spec:
Only one precision control option may be specified by any given
fragment program. A fragment program that specifies both the
"ARB_precision_hint_fastest" and "ARB_precision_hint_nicest" program
options will fail to load.
with the second sentence clarifying what exactly is meant in the first.
