I also really like this form for regular communications, though I use spaces. It feels more natural than ISO format while being unambiguous. You can also add the day of the month and it's nicely balanced between letters and numbers, and you can also drop the year when it's clear from context:
"Hey, are you free for dinner on Wed 23 Aug?"
ISO is great for records and filename, but it's clumsy in conversation:
