nfacct objects already support accounting at the byte and packet level. As such it is a natural extension to add the possiblity to define a ceiling limit for both metrics. All the support for quotas itself is added to nfnetlink acctounting framework to stay coherent with current accounting object management. Quota limit checks are implemented in xt_nfacct filter where statistic collection is already done. Pablo Neira Ayuso has also contributed to this feature.
