Is there some logic to the variation here?
Warnings are not suppressed with scrollmode (I wonder why pdftex does
suppress them unless in batchmode).
Concerning spaces: we're not (even aiming at exact) log compatible.
Warnings, errors etc are kind of normalized and can get intercepted with
lua. Things like opening / closing files - the () thing - as well as the
way names get repported can differe with e.g. pdftex (maybe even more in
the future).
The way tex reports (macros, expansion stuff, boxes etc) we try to keep
as compatible as possible / reasonable.
Backend and engine messages are often independent things anyway.
