Sorry Kevin.......
I prefer Pascal myself or APL 
both of these languages have great futures!
I Do Agree, Noone Uses Browsers Anymore. They've Outgrown Their Britches.
Being able to test your code while you're developing is certainly a hindrance to efficiency. I prefer having to compile and restart - with time to make myself another coffee - to test, myself.
With Python you can do anything. While not out of the box, a blanket statement like this is problematic.
Not sure what you're talking about here, is it numeric formats? If it's styling, then you're most assuredly more wrong than you know. Perspective styles / css offers 500+ styling options all tied into a single style class you can assign to any component. I doubt you'll find that in any other scada.
Is this a thing people do? Sounds very specific.. I think you'll find these other apps don't do that either: Windows, Linux, Apple?, Paint, Citect, Clearscada, "I could go on" (just like my heart). These are only fairly insignificant apps though, so maybe it's expected 
Yet. But it is coming and it will beat anything else you've used in another scada out the park (probably). Have a look at the ICCX (I think) preso with a demo.
See 25:60. Or 26:00 if you're more simple-minded
This I'll grant you (find replace can only get you so far), but with python you can create any tool you like to bulk edit, so it's kind of moot if you have the nous
Yes there is, from 8.1...15? Upwards
One thing that I think we will I agree on however, is the flaw in Ignition that it doesn't make my coffee in the morning
