I'm not arguing that using phone numbers doesn't have benefits. I'm just saying that WhatsApp intrinsically shares your number so obfuscating the URL will provide little benefit. At the end of the day if you want to allow people to contact you without sharing your number you would need something like that I proposed. And in that case you would explicitly be trying to isolate from your other contact methods so your "benefits" become drawbacks.
