Long term, IPv4 allocation won't matter and it's too late to fix that problem
Port numbers are kinda obsolete on the internet since everyone uses port 443 to bypass middleboxes that block all the other ports in the name of "security". Hardcoding a number for each protocol instead of including IP+port in DNS responses was a stupid mistake
All consumer devices being forced to share ISM bands is BS, but let's be real even if more spectrum was opened up back in the 2000s, a lot of devices would still use the same range of frequencies because they wanna use the same cheap ICs and antennas
Good wifi performance requires an AP in every room. The lack of 6ghz penetration is great for high-end setups because it eliminates the hidden node problem
"SRV" records include the port in DNS responses. They've been available for almost 30 years. Unfortunately, outside of a few protocols (SIP, XMPP, etc.) they never caught on.
