The "glass" baffle that you THINK you see are not glass... it is left over acrylic from a viewing/camera box I attempted making 2 months ago.. I never went out and bought new acrylic... My cracked tank is still sitting in the backyard where I left it with all 5 sides intact, cracked, but intact.  
 
You used scrap acrylic on your AIO tank... no different that my acrylic in my sump.  I don't see any between the line rules in that respect.  My sump cost me just over $80 of my budget, and I have deducted it... Whats your point? When your AIO setup cost you nothing with all your scrap acrylic and broken glass.
