are you trying to say a commit libswscale/abc libavcodec/xyz will fail?
if so, i doubt thats true and if it is its a bug/limitation in svn and
should be dealt with accordingly (=bugreport)

if there are no changes in ffmpeg then theres little need for them to appear
there as a change of the revision number ...

same as with mplayer and lavc/lavf, or even all external libs mplayer uses

first requirement: leave me out of this idiotic disscussion
second: distort the history as little as possible

moving sws into ffmpeg will either destroy the date/time of the past
swscale changes or distort the revision numbers

In the past you could go to a library and read, borrow or copy any book
Today you'd get arrested for mere telling someone where the library is
