No, they are not. Again, without seeing actual information from your system it is just pure speculation, but NetworkManager builds these addresses based on machine ID, stable secret, connection UUID and interface name. Unless these addresses fail DAD they should remain the same as long as the listed items remain the same.
I have been running IPv6, with SLAAC, on my home network for 12 years. Yes, there are new privacy addresses every day.
Apparently you confuse privacy and temporary addresses.
I have seen that many, many times. If I were to boot my desktop system today, I would have 1 persistent and 1 privacy address. Tomorrow I would have 2 privacy addresses and so on for 7 days when the oldest one is deleted.
Setting ipv6.addr-gen-mode=0 will change it to EUI64 if you prefer that.
I have considered that. I'll see what happens and if I get both a persistent and privacy address.
