Yes, this provides additional good background.

There does not seem to be any substantial disagreement with the notion that
it is a good, safe, and normal practice to presume that the umask will be 
the controlling factor in determining how permissions are set for newly
created files.

There have been two exceptions noted, one for cp and another for tar; both of
these are reasonable and ordinary exceptions needed for file management, but
they are not typical of most applications.

Are there some additional remarks anyone cares to add to the above?

I will be following up with the vendor this week.
