If you're putting up an rf node that someone else could point at, a precise GPS location lat/long is very helpful ... and it puts you on the mesh map if your region has one (if you upload the data). Lately the ask is that all nodes have coordinates entered, even if they are in a go kit and could move around. Some of the software depends on each node having something entered, so for my go kit stuff I just use my home coordinates. If I'm going to operate for more than a few hours in a temp location I use my phone to get the new location and change this on the node setup page.
