No idea about 12.2, but 11.4 is still in active use. So please keep it.

The publisher knows only about the SLE_11 path. In fact I just removed
the SP3 repo from Multimedia, no idea if we forgot to remove it or if it
was added in the last weeks. SLE_11 and SLE_12 are supposed to be binary
compatible, and only the last SP matters.
