Comment:

 [attachment:37061.2.diff] is an updated patch that preserves the original
 return types (raw objects including the property `userblog_id`). The
 function still uses `get_sites()` as proposed in this ticket.

 While I was at it, I adjusted some docs and variable names to properly
 reflect our current multisite naming conventions. Doing that, I noticed
 that the docs of the `pre_get_blogs_of_user` filter state that the
 returned value should be an array of `WP_Site` objects which is incorrect,
 so I changed it to simply "site objects" as well.
