The availability of SQL access is neither a sufficient condition for a 
database system to be relational, nor a necessary one.

The same can also be said for the lack of availability of other forms of 
access.

You seem to be the only one here with that opinion. And if anybody 
outside the OS/400 world looks askance at the OS/400 implementation of 
DB2, the most likely explanation that comes to my mind is that their 
implementations aren't built into the operating system, much less into 
the licensed internal code.
