In many maintenance situations, _ANY_ source code change is an issue.
The more files you change (in some situations the more lines you
change), the greater the impact - on testing and on cost. Adding
pragmas throughout the code may be as large an impact as a
moderate-to-large redesign.
Another GNAT warning I'd put in the same category is 'object XYZ is read
but never written' (or something similar). I saw this recently for a
record type (defined in a different location), where all components have
default value ... except for one which was added recently.
