Comment (by Connor Worley):

 The vf_scale filter you linked is automatically added to the filtergraph
 depending on the input format:
 https://git.videolan.org/?p=ffmpeg.git;a=blob;f=libavfilter/avfiltergraph.c;h=e4f59f56e2b102372178c693d8439059565d207f;hb=HEAD#l467
 -- this is not always necessary, so it does not always happen.

 Both this and the vf_scale filter are unrelated to the lack of a warning
 in swscale.
