Thread:Talk:Extension default namespaces/Please define a serious range for user

A site administrator need free and secure namespace ranges to use for your site... There are a big contradiction with "The namespaces in 100-199 are reserved for site-specific namespaces, and should not be used by extensions".

Please, if it is a serious standardization, express an ensured range or set of ranges, that not will change tomorrow. EXAMPLE: "dear admistrator, sorry, you can ensure after 2015 with {130-159, 150-159, 180-199}"

Please say to extension programmers to move out from the reserved range.
