Ah, that's a well-known trap. The site you named is notoriusly unreliable, due to their "creative" solutions. In this case they took over the internal reference of another aerodrome repository (to which I also contribute): https://ourairports.com/airports/GB-0843/
With your leave, I'll remove the reference from OSM.
And no, it seems unlikely that this modest farm strip has any other function.
Greetings!
