Carl,
You would think of this in the same manner as you think of someone writing a

script to recursively delete all files in the production directories. In
other words, as soon as

you allow scripts, you need to implement the -ro controls.
Of course, you can always use EPICS access control.

Hi,
Our EDM display authors frequently use EDM's shell widget to run
scripts, including scripts that do 'caput's. Such buttons/scripts
appear to be able to do settings even when EDM is started with its -ro
option. While I can understand why this is so from a difficulty of
implementation perspective it does seem to mislead the user. Are my
facts correct? If yes, what does one do or think about it?
Thanks,
Carl Schumann
