I wonder if I should feel inadequate for having only seven VLANs in my 
two-bedroom apartment. :-)

So this is already happening.  Or at least it's happening in Hong Kong.

The Wi-Fi scan list in my living room shows a roughly equal number of 
"FOOBAR" and "FOOBAR-GUEST" ESSIDs.  There are several different 
spellings of FOOBAR but they all translate to "cheap ISP CPE, settings 
not touched by customer".

The CPE my ISP tried to install for me has a friendly "guest Wi-Fi" QR 
code sticker in the box.

Casual inspection suggests IPv6 prefix delegation is taking place and 
the guest Wi-Fi is a separate layer 2 broadcast domain.  I never paid 
much attention to the legacy IP address.  I'm pretty sure there's 
routable IPv4 rather than XLAT though.  I never used my ISP's CPE and I 
don't make a habit of spending too much time staring at tcpdump when I'm 
invited to dinner by less technical friends. :)

I wouldn't be surprised to see a (probably small) decrease in fixed line 
broadband services in some parts of the world.  People who don't have 
own huge televisions or smart hair dryers or toasters or whatever have 
no need for fixed line broadband.  They watch YouTube on their phablet 
on 5G.
