By that argument, you wait until lots of people have problems before
you change the default to accomodate them, instead of thinking ahead.
If you want a simpler default, can you not follow the instructions
and give yourself one. For people upgrading, Debian ensured that
there would not be an unexpected change; the older methods prevail¹.

It's the *only* source here for such as 192.168.1.13	wasp
but I was assuming you'd understand I was talking about non-local
hosts on the Internet.

Yes, and I remember the problems I had when all my NICs were
3c509s from the free shop (Academic Computing Services) and
I put two in the same box. These (problems) would be unacceptable
nowadays.

You can't please everyone. You can find threads here complaining
loud and long about udev's persistent-net rules¹, one of the
preceding methods "foisted" on us by Debian.
