I was being non-precise. If leap seconds are abolished, then the start of day will start to shift and eventually midnight will be in the middle of the day. The wider world has certain expectations about the meaning of midday, midnight, and when specific times occur. Just allowing midnight to continually shift isn't a valid solution to the problem. >> - TAI - simple incrementing number that is well-defined (although >> clearly not everyone here will agree with that).

As discussed on another thread, I need a scale synchronized with TAI at the moment, where the number simply increases continuously without breaks one SI second at a time. Since this can't be defined clearly in the past or the future, the best solution seems to be to call the scale TAI-Java.
