It isn't about "more procs to track"; abilities need to fall into one of three categories to be valid; they need to be useful, provide depth and/or enjoyable. I don't think Flurry fits any.
Useful
Pretty obvious - I would put this in the vein of things like Utility. They could have removed BzR completely instead of just removing Enrage portion, but it gives us utility and thus is useful. Obviously this falls into the context of balancing; can't champion adding everything under the sun because it could be useful, but you get my point.
Depth
Again, obvious - Colossus Smash adds depth, even if some people don't like it. The relationship between Crit, Mastery, Enrage and Raging Blow for Fury provides depth; it doesn't for Arms, hence why I was championing for its removal or redesign.
Enjoyment
Here is where people will get confused - You can call that psychological feeling from Flurry "enjoyable"... but is it really? You don't notice it proc, so the only thing you ever "feel good about it" is when you specifically think about it, or when you happen to glance through your spellbook.
Of course, enjoyment is very broad, even something as simple as a visual proc can add enjoyment and maybe that would be enough to save Flurry; but right now it has 0 enjoyment.
