Good catch.

IMO we should allow more space for specified QOSMs.  7 seems like insufficient space for future growth (recall that 0 is assigned as the default QSPEC Type).
 
One alternative would be 
 
0 = default
1-12: specification required
12-15: local/experimental use

 
IMO a better alternative would be to expand the space for QSPEC Type, as follows:
 
In Section 5.1.1 reallocate 7 bits to QPSEC Type as follows:
 
 0                   1                   2                   3
 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
|  Vers.|I|  QSPEC Type |  QSPEC Proc.  |      Length           |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
 
And reallocate QSPEC Type bits in Section 7 (IANA Considerations) as follows:
 
 QSPEC Type (7 bits):
   The following value is allocated by this specification:
   0: Default
   The allocation policies for further values are as follows:
   1-31: Specification Required
   32-63: Private/Experimental Use
   64-127: Reserved

Thanks,
Jerry
