This is correct; while the software I write for my employer does not
use TAI, we use a similar timescale of our own devising. So it is not
unusual for applications that need to know about time to use a
timescale without leapseconds internally. So there is other software
out there.

It's too hard to write decent timing software using the ntp/unix
timescale - all the discontinuities around leap seconds make the code
prone to errors.
