No, libswscale does not suffer from the same issue of being a secondary 
filter library. See for example how libavresample is the secondary 
resampling library, which has been deprecated for being regarded as 
worse than libswscale. libpostproc is just another filtering library 
(which was shoved into lavfi instead of its filters being moved into 
lavfi). Some of the postproc filters seemingly have equivalents in lavfi 
(just going off of names), so I think removal of postproc while making 
sure equivalent filters will be available is the best way to solve this.

I'm unsure of which multimedia standards you refer to.
