I just realized something...its funny now that I think about how I could have missed considering it so far.
When in urban/CQC situations, it might be preferably for shooters to go with a rifle that they can easily switch hands with (when you're a right-hander but are approaching a left corner for instance) for some additional control over just how much of their body they're willing to expose out of cover (it'd be a lot more if hand isn't switched).
On an M4, AK or any traditional-layout rifle, this is rather easy...
Not so with Bullpups* - and not with the Tavor in particular. Unless one wants brass & gas thrown dangerously close to their face and I can understand if someone doesn't want to put up with this nonsense if they can avoid it:
^^ Not that it can't be done, but no way that can be comfortable, or safe even. Especially if without a mask+eye-pro.
Only way to avoid it would be to sit down in combat and proceed to switch the ejection over to the other side xD
* The FN2000 for example ejects from the front, so not that big a problem for it.
