I completely agree that the best setup for renderers and routers is to have both:
- a landuse area to denote the boundaries
- a node with place=neighbourhood to mark the community’s center and its attributes.
This is consistent with how provinces/districts/towns/villages are tagged.
Alternatively, these are acceptable intermediate solutions currently in use:
a. only a node with place=neighborhood when the boundaries are not known
b. only an area with landuse=residential + place=neighborhood when the center is not known
A landuse=residential area without a place tag should not be recommended as it will lead to confusion: is this a village, a suburb, or a random group of buildings… ?
Adding the extra tag place=neighbourhood removes the confusion and the tag can be easily extracted with other attributes (name, operator) when adding later a node at the “center”.
I have asked the global community site for their expertise on this topic:

Though, I wouldn’t put too much hope on new tag proposals as these are difficult to get approved.
