100% of the changes will be declaration of the variable and if statements.
No error messages and many other messages will not have associated if statements.
The initial value of VERBOSITY will be such that no existing print statements will be suppressed, so nothing will change if there are no -q in the command. This would open the door for new prints that do not show up without a -v.
Regarding my use case, I use the optional rawml output to help fix xray entry errors. I've found that a 2 line sed command can make the rawml viewable in a web browser.
Code:
s/^<?xml/<!--l/
s/dtd">/dt-->/
I also have a simple script that bolds, tags, and numbers all the entity occurrences in the rawml.
The printout for every image in the book is what I particularly don't want to see.
What's in it for me is not having to redo the changes every time a new version comes out.
