I kinda agree with this, but mainly because there aren't really any other than BW that screams BM-only.
The breakdown for spec-specific glyphs:
All minor glyphs are non-spec specific btw..
MM: Prime - 3 (Aimed Shot, Chimera Shot, Dazzled Prey
Major - 1 (Silencing Shot)
SV: Prime - 1 (Explosive Shot)
Major - 1 (Wyvern Sting)
BM: Prime - 0 (Yes, big fat zero here -_-)
Major - 1 (Bestial Wrath)
Every other glyph is available to all specs and affect baseline abilities.. I think part of the reasoning behind the lack of BM glyphs is the lack of active abilities that the spec has. But don't you think that Blizz could at least toss a Prime bone and give us something BM specific? Maybe even something sexy like giving a moderate damage component to Intimidation <,<;; I'm sure that would make all of us who are looking forward to playing BM in places other than obsolete dungeons giddy with joy. (Seriously, if it added damage equal to a single Steady Shot, would it really be that big a deal?)
Ye im happy with what they have released to us so far but as people have already said there does seem to be a lack of BM glyphs and especially prime glyphs seem far from complete, just hope they get the glyph vendor out on the PTR soon so i can start testing some of these out
