I didn't say there were no use cases for this, but the average phone user will not need it. someone using samba on their phone would likely be capable of switching the network config to not randomize every time.
for a device without inbound connectors and no ip based lan firewall rules, which applies to most phones, random per connection macs seem like a pretty good default for privacy.
some networks doing "unusual" things like hotel wifi limiting you to few devices (implemented by mac counting) may be thrown off though.
