This is why the split up of observable data between debug & creation data
was introduced, along with the ability to remove these observabilities
individually. 

QFRCCVNRST can cause the recreation of the "executable" from the creation
data. IBM forewarned of this a few releases ago, I think in the Memo to
Users.

If you are still creating programs on or for an old release (V2R3 IIRC) then
these won't have the observability split up.
