Not much value I'd think. Plus a handgun red dot is $300+. Add $300 to whatever your carry piece cost anyways and then think about how well the police would handle you gun.
Personally, I place zero value in that part of the argument -- if I have to use my gun in a self-defense situation, I want the best one I can get, with every advantage possible. You can always buy another gun.

I can't see myself ever doing it. There are a few failure modes with my metal night sights on a carry pistol. One is degrading of the Tritium, at a known 12 year half life. The other is falling off. Putting hundreds of rounds down the pipe and practicing single hand racks, etc. have proven to me that they are solid.
Now the failure modes of a red dot rear sight. Battery, impact, covering emitter, turning off automatically, dot too bright or too dim for current situation. Lack of common over the top power stroking of the slide.
Why do you see RDS and irons as mutually exclusive? You can set up an RDS to cowitness with irons on a pistol just like on a rifle.
The discussion for this started with a RDS that essentially replaced a rear sight. I guess that is what got me in that mindset.
I'm for tools that are simple and work well. I don't see a real advantage for a RDS or laser at typical self defense distances.
Perhaps even one day we won't have a need to project the dot onto glass, but could rather have it suspended holographically just above the slide.
