I didn't know that this was part of WHOIS, I thought separate services such as BGP looking glasses provided this. And other organizations (IANA and RIRs iirc) hand out AS numbers and prefixes. But even if it were part of WHOIS, then this is non-personal information which should be fine to list in a public directory.

Presumably that doesn't entail saying "you must provide your true mailing address, name, and phone number or we yank your domain". A working email address should be all that is required, at most.

These decisions don't touch upon the listing of corporate information. Unless a private person operates an AS, this is not an issue for the things you mentioned.
