I have the urge to grab a pitchfork, but I know better than to make assumptions about why that functionality was added. Time to do some homework I guess.
I really dislike the complexity of modern C++ language specs, but does it obscure much detail about FP ops?
TL;DR:
A vast majority of the programmers I've worked with don't understand the nuances of FP in general, nor the various extents of IEEE-754 support in different programming languages.
So for important numerical programming, I think clarity regarding the FP operations being performed can be crucial. I'm just unclear if modern C++ is a significant factor for that.
We want to perform our work skillfully, effectively, and professionally. But we never want our tools to actually be needed.
(Another is that we can't effectively create a shield without the risk of it being used as a sword.)
