Heya, wrt https://www.openstreetmap.org/node/3071545092, mapping a cattle grid and adjacent gate as one node is a pattern which National Trust have been using quite a lot in their recent edits to add walking routes in the area.

If it’s something which you think should be strongly avoided, you might want to drop user NTTrailsLSE a message and work out an alternate tagging scheme with them. :)
