Unix time is bad and needs replacement, not UTC

I see leap seconds as regulatory capture by astronomers :D Basically it's convenient for them to have civil time (UTC) never more than 0.5s from UT1.

Astronomers don’t care, they already need 5 different clocks.

Also the allowable variance between UTC and ut1 is 0.9.

Exactly - and if astronomers don't care, what other reasons are there to require accurate synchronization of UTC (and civil time) with earth's rotation?

Considering the rate of progress, timestamps might need to be replaced with reference-invariant coordinates.

Or one clock that can switch between 5 different times.

I didn't necessarily mean 5 different timekeeping devices (though that would probably be more convenient in many cases), rather than an astronomer needs to keep track of multiple different "times" concurrently.
