I think I read somewhere that older tanks pre 1970's? didnt have to have center braces as the glass was thicker back then, but since you said its a newer tank I have no idea why it would not have one...
Actually my 75 has the centrer glass strip. Has it from the manufacturer so it's not a hack job.
absolutely, plenty of manufacturers don't use a center brace due to the factThere is at least one manufacturer that makes 75 gallons tanks without any form of center brace. My local lfs ordered some for the local university and I just happened to be in the store when they got there. I was curious as I hadn't seen one like that before. I think they used thicker glass. The tanks were pretty heavy.

they use a thicker glass, to compensate for stress at the weakest point.
even acrylic tank manufacturers integrated top braces, to reduce cost.
but a thicker perimeter acrylic negates a top braces.
a siliconed in glass to glass, glass top brace might do in a pinch, not a manufactured stand point.
the question still stands.
"what manufacturer is that?"
"how about a photo? "
