For applications where the aim is high sales volume and low support, you're absolutely right.

But "development/debug tools" is actually just a subset of professional or industrial utility applications where user count is low and support is on the extremes (either "capable self-support" or "Yes, Bob, of course we'll add that for you").

And in those utility applications, you probably don't need the noisy toy animations associated with modern consumer software, but animated data representations can be really valuable.
