(I can only guess because I am not on OS X.)
By default, hwaccels are enabled / autodetected. Since you did not 
disable hwaccels, h264_vda was detected and enabled and since it 
required the h264 (software) decoder, this decoder was also enabled.

I do understand why you suspect a bug, but it can be argued that 
this is intended, if you want to disable the software decoder (and 
don't need h264_vda), use --disable-hwaccels.

Could you explain what you are trying to achieve with --disable-decoders 
--disable-encoders --disable-muxers? If you only need demuxers, I 
wonder how good they work with --disable-decoders...

Note that there is --disable-everything (which can be combined with 
enable-options) which you may be searching for.
