How did you come to this conclusion and the number of media files?

Wiki lists less then 2.000 files.

https://wiki.openstreetmap.org/w/index.php?title=Category:Media_without_a_license

I think, that based on the history of the wiki and it's CC-BY-SA that 
most of the uploaded content was actually intended to be exactly that.

Was it really clear from the beginning that all uploaded media need a 
dedicated copyright statement? Potentially they are left-overs from that 
time.

Just picking a file of this list which looks obviously genuine and 
intentional, the following is an example:

https://wiki.openstreetmap.org/wiki/File:Alen_self_photo_192x192.jpg

File is only used on a user page and uploaded by the same user stating 
it is a self photo.

If it is important to have an additional note on each upload, we have to 
make sure that this is enforced on new media upload. But why not assume 
that old one was correctly uploaded as CC-BY-SA?

"Content is available under Creative Commons Attribution-ShareAlike 2.0 
license unless otherwise noted.". It is not noted otherwise, so it is CC.

As wiki has a disclaimer, that it is about OSM, I do not see the need to 
add attribution to single tiles in this context, as it is used to 
discuss/document OSM mapping.
