1.93" height mounts, why all the excitement? Where did they come from? What was their original intended purpose?

These mounts seem super popular these days. Initially i read about seeing over IR lasers and being high enough to use with BNVG.

So that kind of made sense, but with an absolute cowitness mount and an Aimpoint T1 I have no real issue getting a sight picture with my nods. As the the laser, my PEQ15 blocks a little of the site picture, but nothing I don't think a a 1/3 height mount wouldn't fix.

Now I see 1.93 mounts for LPVO, and people waiting to get a mount until a 1.93" version comes out.

So I ask why?

Why 1.93", that seems a very specific height, where did that come from.

Why are people really so excited?

Why would you use it with a LPVO?

Doesn't it suck having a high site over bore?

What am I missing? I feel as though there is something I'm just not seeing
