The issue that 128bits (64+64) are wasted in every packet. Formally, for "privacy".
Content providers are lathing from such form or privacy.
But it is 2% of the internet capacity.

I do not understand what you are talking about.
IPv6 is mostly using SLAAC. SLAAC is 64 bit addressing architecture.
(by the way, 64 bit is enough for addressing of everything) Even if
somebody use DHCP, he typically makes subnet "SLAAC compatible", it
means: use 64 bits for addressing.

Where is the issue there?
Unless the A-bit is set for the prefix in the RA, no machine will do autoconfiguration using SLAAC.
