I feel like if that feature had been removed, it would make locations and travel far more significant.
I remember sailing the seas with my boat and the sense of exploration I had by visiting islands few people had been to.
I also feel like there should have been consequences for logging out in the wilderness, perhaps a strong chance of waking up to some monster encounter and with less than half your HP when you log in. This would incentivize people to seek towns or homes or at least use the camping skill.
I think UO really shines when you lean into hardcore elements.
