Astronomers whose software uses UTC and isn’t able to change to UT1, and who don’t need precision less than 1 second, but more than 3-5 seconds or so will be worse off. This seems like much less net inconvenience than what the tech industry has to deal with when it comes to leap seconds.

I hear the argument that we have to deal with this eventually to keep time in track with mean solar time, but the adjustments are so small that I don’t see any real impact on regular people.
