This change is not clear to me: which trac instances are affected? The
sentence above is not yet clear to me.

If project trac instances are affected (how?) such change needs please
to be communicated before changing anything,e.g. through the
"projects" ML.

thanks,
Markus

PS: For example, the GRASS GIS project depends on trac notifications
to be able to work.
