The problem is that some people use UTC to mean "TAI plus adjustments to
keep it less than a second from UT1" while other people use UTC to mean
"the basis of legal time here". For the second set, using a new name for a
different concept doesn't help.
There are good reasons for wanting legal time to be TAI+<n>+<local offset>,
where <n> is a constant (somewhere around 35?) that never changes in the
future and <local offset> is chosen by the relevant lawmakers and is normally
a multiple of 15 minutes. If you accept that these reasons override those
for keeping leap seconds, then a name change won't make it easy.
