Please explain your feature request to the best of your abilities:

right now theres no real good way to give chunks to other towns, maybe add a new perm node town.cede where you can do /plot cede town_name and it is given to the town

We still struggle with this and have had to make it a manual Staff task to exchange chunks for towns using the /ta set plot command if mayors request it.
I still think the best way to fix this would be to make towns able to sell plots to other towns, while only requiring the towns to border each other. That would ensure that both sides want it, adds an automated economic perspective to it and with no major distance rule issues since they were already neighbors.

Whats there to lose really? The perm wouldn't even have to be given by default, so server owners can at least choose whether to have it or not.

Oh? Sorry I didn't know that. You implemented my suggestion last week so had no idea there was an issue with me.
I just thought your earlier description sounded a lot like my then-sponsor suggestion #6295

This gets a bit hairy in that there's all sorts of rules about distances between towns.

Before I add this I would want to have the code consolidated to something so there's no duplication of tests so things can stay consistent going forward.

FWIW admins can flip plots for towns using /ta set plot [townname] for players that want to do this now.

What's wrong with unclaiming and having the other town re-claim?

I've had other people want to have something immediately flip plots in the past, where the server uses the revert on unclaim or plot-clearing features and unclaiming results in blocks being displaced.

#7151 is my first step towards making things a bit more uniform as for whether a plot should be allowed to flip to a different town.
