There is a bit of mismatch between the two questions, one in the title and one in the body of the question.
There has been a review, and it is the report linked in the question itself. However the report is heavily debated, one may follow the debate by looking after the publication "The ICTY prosecutor and the review of the NATO bombing campaign against the Federal Republic of Yugoslavia" (Benvenuti, 2001) and the academic papers citing it (which are 138, according to Google Scholars).
Main point of the paper here linked are the followings:
The author analyses the report on the NATO bombing campaign against
Yugoslavia, prepared by the Review Committee created by the ICTY’s
Prosecutor, and observes that the recommendation that no investigation be commenced because ‘either the law is not sufficiently clear or investigations are unlikely to result in the acquisition of sufficient evidence’ appears prima facie questionable.
Unbalanced evidence on which the Committee’s statements are founded
and by the restriction of the collateral damages of the campaign to
the civilian casualties.
The Committee’s assessment of general issues (damage to environment, legality of weapons, target selection, proportionality) [...] deviates from well-established ICTY case law.
The Committee’s
assessment of specific incidents is also characterized by
shortcomings: inter alia, the report frequently slips from the level
of individual criminal responsibility to that of state responsibility.
So there is no proof that the legal debate has been brought forward, but there is some (peer-reviewed) discussion on the topic.
