In osCommerce, the path for all the major folders are set in a config file, which then allows for moving those folders (admin, images, includes etc) anywhere the site owner wants within their hosting space. It also allows for renaming the folders from that same central file - so for example if you wanted to obfuscate your admin folder identity by calling it something like "switches" or "interchange" or whatever, the site owner can do so. The folders are assigned a string value in the defines, and the value is then called each time a script file needs it.
Although WP has a path field for the uploads in the admin, there seems to be no other possibility to obfuscate or relocate / rename key folders such as wp-admin or wp-content.
This is starting to emerge as a serious security flaw in the WP architecture as other recent threads in this forum have revealed (regarding a particular backup plugin's past behaviour).
Would the WP devs like to take this thought into consideration and post back with a confirmation that custom pathing will be available in future releases of WP?
