Outside of England UT isn't the relevant timescale for most civil and
legal purposes; local time is. The recent efforts of the Australian
legislators certainly hampered any kind of countdown until a given
local time.

I am at a loss to conceive of any application which needs an
unsegmented, predictive countdown of UT to an accuracy of one part in
1e7. Please given an example of where such would be used.
