That's a nice touch.
Just be aware though that it could come back to bite you on the bum in future, if someone decides to claim a legal right of access through continuous usage. They'd probably drop that bombshell (in order to protect their interests) at the point that you decide to sell the property, which would seriously affect it's value.
In all honesty. I'd be quite happy with that , and if I did sell the land, I would have it written into the contract, that they kept a right of way through the land (as they walk through to visit the neighbour on the other side of the land), although , if it was used and abused by hundreds of people every day , I might see things differently.
When we first bumped into the owners of the neighbouring land , I offered them access , and use of my land , this was immediately welcomed by them , with an offer for me to use their land as well. We've now become quite friendly with the neighbours, and they often pop into the woodland when we're having a bbq , or doing a few targets with the guns . They've also told us where they hide the spare key to the house , so that we can use their landline , or stay at their house , should we ever get into trouble when they aren't at home .
Several other benefits of being friendly with the neighbours, are . Whenever they visit , they bring homemade, flapjacks , cakes , jams , and also , they used to be totally anti shooting townies , but now we've spent hours upon hours talking about shooting , and other fieldsports , they happily accept , venison , pheasant, trout , and have a much greater understanding of shooting folks.
