I'll see how it works.
10 days later, I have not seen any problem running with Mac randomization, and I use Wifi every day.
On the 'getting the list of stations' subject, I have noticed something new: when I go to Wifi settings and there is nothing displayed (except the access point the phone is connected to, that is), if in a (ssh) console I enter
sudo iw dev wlan0 scan
the phone screen displays magically the list that was scanned. I don't know what this could mean, maybe the list is cached somewhere and sometimes the cache is stale and not refreshed automatically or it's something else. The cache hypothesis is confirmed just now, I had left displayed a list of wifi stations, left the phone rest for some time, after unlocking it the list has disappeared.
There is a wrinckle though: sometimes entering the refresh command, the reply of the command is 'scan aborted!'. This could also be what happens when it does not work. Unfortunately in both cases, the command is displayed in the system journal, but when something goes wrong nothing more is displayed. Sometimes the list vary from one execution to the next a few seconds later, but maybe it's because it's radio after all. Or there is a too short timeout. More investigation is needed (but I'm not giving up, this is only a follow-up).
Last thing: the 'scan' command has a [randomise[=<addr>/<mask>] flag, so the randomization can be at 2 levels (scan and normal use) and can not to be done at the scan level, although I don't see why this could have 2 different results on 2 configuration that seem the same. I don't even know why there are 2 levels in the Mac randomization. The only thing I know for sure is that there are some wifi hardware/firmware/driver (?) that do not support Mac randomization (because I have read it in the configuration files for the FP5) so it could be remotely possible that some configuration don't support the randomization at the scan level while supporting it for normal use.
