You're right.
It's a known and big issue.
FSTrigger belongs to the X-Trigger typology through XTrigger plugin.
XTrigger plugin enables you to poll changes from an environment which can be a filesystem, a build result, a binary repository and so on.
Having a complete diff in order to have a change log as you have for a SCM polling is very difficult.
We have difficulty providing that because we don't have any way to lock a state such as a tag (label, baseline, ...) in SCMs.
In a first time, I'll provide the change log (the reason that have scheduled the build).
