What a shame - I don't remember anyone asking for this? Was one of the more interesting things to happen out in the black.
Just looked at the last two pages of responses - there are certainly people who want this, and it makes some sense for 'real' explorer who run the (small) risk of having a long trip wrecked due to circumstances they cannot control (though I don't think it's them complaining). I'm against it as it will slow down long distance travel, but it's not that much slower and people will get used to it.
Long distance speed records set before 2.4 might stand for a while unless the 20k ly plotting tips things in the opposite direction - time will tell.
