The question as phrased at the beginning of this thread is inaccurate.
The discussion at phabricator is *not* about "What should be the autoconfirmed age and article count in the Hebrew Wikipedia". The request there is twofold:
1. To create in Hebrew Wikipedia an "extendedconfirmed" group, the same way it exists in English Wikipedia (and others). 2. To have the "move" and "editsemiprotected" permissions transfer from the "autoconfirmed" group to the "extendedconfirmed" group.
No one is asking there to change the threshold for the "autoconfirmed" group.
