 From a technical point I absolutely agree with you.

However, there have been discussions (IIRC on the TZ or leapsecs mailing 
lists) where folks tried to explain that even though the difference 
between TAI and UTC is just an integral number of seconds, TAI could not 
even be used as a replacement for UTC without leap seconds, just due to 
specific wordings in certain documents.
