Regarding your first point, it does refer to mapping practice, not wiki contributions.
Regarding your second point; firstly a hotel doesn't change purpose based on who occupies it, and secondly under the "Other Concerns" section, we have:
"- Safety concerns. This would apply to, for example, mapping the location of safe houses for victims of domestic violence, or places of worship of a religion persecuted in a given region.

    Such places will also not be signposted, so it goes hand in hand with verifiability. Note that a signposted place for victims of violence wants its location to be known, and mapping it would help, while mapping a secret safe house would cause problems - and would violate the verifiability rule."
