Of course it is done!!!

You have definitely never read any paper about astronomy, or the history
of astronomy. As a matter of fact one of the main issue in astronomy is
to determine the distance of objects as precisely as possible.

And for amusement: noting different delays of quasar fluctuations,
in passing through an Einstein lens, is a practical way
of establishing their cosmological distance,
Sure, the delay is known.
But how would you remove it?
The difference in time is actually HUGE, hence you would need to wait a VERY long time, if you want to know the present position of stars seen a few billion light years away.
In the meantime cosmologists explain the positions of stars, which do not belong to the same time.
