I wouldn't quite go as far to say that it is a "boot loader".  It does 
load Windows NT & then disables services and features which are not 
firewall related or have been deemed to be insecure.

Granted, however, the first release of any product is always missing 
some features.

Personally, I see this as an advantage rather than a disadvantage.  I 
wouldn't want to use any NT features which may be critical to the use 
of the firewall for two main reasons:

1) You can't be sure that the software will be stable.  
    Micro$oft could accidently let a bug creep into their software 
    which could render the firewall insecure or inoperable - requiring 
    that the vendor "freeze" their version of Windows NT ("We will only 
    support NT version X.Y.") - leaving them in a strategically vulnerable 
    position.  

    Also, if the software is written internally, then you have full 
    control of the s/w development, you can provide better support, 
    and you can provide a quicker response to problems/bugs.

2) Security
    Pretty much the same rasons as in #1.  Further, it is never a 
    good idea to outsource Information Security.  Relying on Micro$oft's 
    security mechanisms would place the vendor's product & reputation 
    at the mercy of Micro$oft's ability to write tight secure code.
