A misjump in canon is not an 'adventure' but certain death with no out option. It is a game feature incompatible with Traveller design thinking as I knew it in the 80s. It is therefore something to be fixed, because no group of PCs would want to be told 'game over, all dead from boredom'.

PC death without recourse is a feature seen in other 80s RPGs also. In fact, CT character creation rules support this "high mortality rate" style of play by making it simple to roll up new characters. There are a number of other RPGs (e.g. early editions of D&D, Call of Cthulhu and the Warhammer 40k games) where character death is a feature of the systems themselves.

An argument could be made that newer editions of Traveller perhaps retain the mis-jump rules out of nostalgia, but probably more accurately they are there because they exist in the OTU.

As has been mentioned already, mis-jumps are easy to avoid with basically maintenance, but if they don't fit into YTU then just ignore them. There are plenty of gamers who prefer their games quite gritty and their GMs unforgiving, and the chance of character death high.
