Its a good thing for a training environment,
You have to sharpen up your RT, situational awareness,
I think in EGHH case, ATC will also have to sharpen up if the first quote is valid. Otherwise, bring a good book to read while you're at the hold and make sure that your passengers can tolerate going round and round at circuit height without feeling sick.
Still, it might be good for Compton Abbas and Old Sarum.
