So, if you keep the feature, and keep it as is, imo it should not be 
officially documented

Not using "execstr" would keep the warning message mandatory -- possibly 
empty "": Why not, ok
(but then "" would still display the "WARNING:" header, while we could 
wish to remove it to fully
customize the display.).
Then, it shall become possible to provide any series of instructions, 
not only the name of a callback function.

Future evolutions and adding argins should not be blocked/made hard due 
to hard argin list analysis.

About the warning level=notices level: i wondered about this recent post 
on users@ about removing
the verbosity of the external modules loading procedure, as an example. 
(by the way, a "modulesload"
common tag would be nice :))
