I have not yet a strong opinion on it.
More often than not, its presence just created small problems, like the one you reported, but sometime it also spotted real issues and proved to be useful.
I prefer to keep it there for now.

I completely forgot that line... I got so used to that message not being correct in the past that I even did not check the rules... Sorry about that.
It is fixed now.

It is a little bit weird, I agree, but is also very widespread in the speech community.
Actually sphere is a container and not a codec and its direct competitor is Wav. The long and detailed header usually contains a lot of information about the recording
environment and this explains its large usage.
With respect to flac (the container, not the codec), it is able to contain A-law and u-law streams (useful when studying telephone speech) and shorten
(http://www.etree.org/shncom.html, used by some widespread speech Corpora, especially those from LDC).
If I remember correctly the ogg container is able to contain all the streams (probably with the exception of shorten) that can be contained by sph files and probably it is
also able to contain all the header information, but I am not sure of this and the format is much younger.

Fine.
Bests,
