There's also the ill-fated Swatch Internet Time, which was a decimal system that divided the day into 1,000 beats and no time zones. https://en.wikipedia.org/wiki/Swatch_Internet_Time
They even sold physical watches with this design.

But the idea of the universal decimal time is a nice one. I wish we had something like that.
Most people don't care about those things though. How does a Casio watch deal with leap seconds? How does a Rolex deal with them? The barrier to adoption is going to be social and not some obscure technical objection by the IAU.
Beats is a new time measurement system, not just a new clock. So if the world (IERS) would stops it, they would have to have new rules for dealing with leap “micro-days” or “mili-beats”.
And second is the fundamental SI constant, quite a bit of stuff is derived from it.
