What are the advantages for this?
I prefer this over being told what I may map and what not.
Does that not depend on whether you are working for yourself, or as a
part of a cooperative project? Do you not care whether others can use
what you store? If you are simply working for yourself, please use your
own database. If you are happy to share with millions of others, please
acknowledge that there must be a certain level of governance to stop OSM
resembling a landfill site.
Nobody limits *what* you map, but if you map things which have a broader
significance than your personal hobby, then there may be
rules/conventions/guidelines on *how* these features are represented
within OSM. And if such governance does not yet exist, it should be
created.
Currently there is little governance within OSM. This situation cannot
persist much longer or the whole project will implode. Anarchy will
produce "WOM" - Write Only Memory - whereby everybody adds their own
little bit of information using their own ontology, resulting in minimal
data quality. Mappers can do what they like, and users of the data (in
decreasing numbers?) do their best to make something useful out of the
ratatouille. The size of the main database will be much larger than
would be needed with stricter data modelling, resulting in sub-optimal
performance, which once again will tend to frighten people away. So
let's just accept that some degree of restriction is 1000% inevitable.
