In case Neji does read this, I'll summarize the counter-arguments too...and I also emphasize they aren't meant as an offense to anyone, regardless of how they may sound >_>
To put it simply there's no real point to restore Oto, since for one there is no buff to give them since the main villages have all 5 in use already, and anyone can travel there now since buying the map is no longer required, its not even an expensive travel and you can get there from basically anywhere. If that isn't enough you can now also scry it through the gypsy tent no problem, for just a smidgen of gold.
I mean, to be blunt, there's plenty ways to get there, clan halls can be accessed from basically anywhere too, even shades, so...isn't demanding even more kinda just the laziness talking?
As for an RP pov, Otogakure never was a real village in canon, just a fake name for Orochimaru's various labs and experiments/freaks. In-game village of birth is already basically completely inconsequential RP-wise, has been for a long time, so what purpose would adding oto to that list serve outside of feeding the nostalgia of either current or former oto people?
Nothing really. And as aforementioned it wouldn't change anything RP-wise either, because one can already do all the RP possible from basically anywhere.
There is one thing I will agree on though; the event about the vendor selling a map to Otogakure should be turned off. Going there hasn't required it in a long time, isn't going to again either from the looks of it, so currently the event serves no purpose other than a hoax to eat up a load of your gems for nothing.
