How could it not be a compromise? If I use a global unicast prefix, the IPs I see on my devices are their real honest to goodness routable IP. That is great! But I can’t use that IP in any configuration because it will change. That’s not so great. So I have to compromise by not using the routable IP in places where I need to put the address in a config file. Nobody wants ULA. ULA is a solution for the fact that your prefix will change, which I wish didn’t happen. You can say it’s unreasonable to expect a stable prefix (and we could argue about that all day) but don’t pretend it wouldn’t be massively beneficial if I could rely on one. It is absolutely a compromise. A necessary one? Yes. A reasonably simple solution to implement? Yes. But it’s still a compromise.
