The USNO predictions in IERS Bulletin A have been pretty good...

https://www.ucolick.org/~sla/leapsecs/bulla52w.html

It will be interesting to see what kind of consternation arises
if the predictions start saying the negative leap is impending.

Somewhere in USNO/UKHO somebody has been making longer term
predictions for use in the navigational almanacs, but as far
as I know those have never been published.
