I’d say the main problem is that it doesn’t work while operating a phone single-handed, when you only have a thumb available, but on iPad I can see it being useful after some getting used to.
I tried on an iPad. That works but it’s really not a good experience, unless I’m doing it incorrectly. On an iPhone it’s also pretty awkward, I don’t think I will ever use that feature but it’s good to know it exists
On an IPhone and I struggle with the trackpad mode as well. I frequently might want to select a block of text, but the OS really only wants me to select to here and no more. Cannot pin down what arbitrary threshold I am missing.
