So far the existence of such equipment in contemporary power
grids is not really proven, is it ?

I know they try to hold the frequency and that they use UTC in
various forms for that, but not phase is not linked to UTC in
the sense that a synchronous clock would "loose" the leapsecond
at some point in the future.

Never attribute to malice what can adequately be explained by incompetence.
