I think nobody thought they had to deal with TAI when the packet format was designed. Support for TAI offset was introduced much later, in NTPv4, when autokey and support for the NIST leap second file was introduced. BTW, it's also an advantage that the packet format hasn't changed. With PTP/IEEE1588, where not even PTPv2 is compatible with PTPv1, even though both standards are new, compared to NTP, NTP packets have been compatible across several protocol versions, for many many years.
