You're right about the hebrew, sorry. Arabic also often avoids geminate gutterals, but allows them time to time. I wonder if it's because they're difficault to pronounce, or because noone wants to hear those sounds for longer than one has to, lol.

For the single pharyngeal phonemes, sure, but Hebrew phonotactics
doesn't allow geminated gutturals, and the guttural category includes
