Stay home or stay at home? Is the preposition on its way out?

It’s really interesting to see how language is changing in the current #Covid19 crisis.

The BBC news app tells us that people are being told to ‘stay home’.

On the signs people have been making for their windows, you can see the appeal of the symmetry of

STAY
HOME

four letters apiece.

Anyone in the UK feeling like there’s a word missing?

STAY
AT
HOME

Are we not liking this?

Is the preposition ‘at’ on its way out?

I know there are far bigger concerns at the moment than the use of a two-letter preposition.

I’m a descriptivist not a prescriptivist, so it doesn’t bother me either way.

I just find it interesting.
