Welcome to the abstraction of rules. Some things don't make absolute sense, erring on the side of simplicity rather than emulating real life exactly. There are dozens of factors that result in olympic world record setting jumps in real life. In D&D, there are 3. Speed, Str, and Skill. Size actually doesn't play an absolute role in it (except where speed is adjusted by size). A goblin is small sized with a speed of 30, and can jump just as well as a human, assuming equal skill and strength, despite being 2-3 feet shorter.
So no, the jump rules don't perfectly model real life. Yes, some things do get left off. I don't know WHY the 3.5 rules left off the 3.0 rule that limited jumps. Maybe it was a simple copy/pasta editing error, maybe it was intentional. We'll never know. If you want to house rule it in, go for it. In my experience with 3.5, however, it almost never comes up for 2 reasons. 1st, most characters don't have the ability to jump further than the old 3.0 rules limited you to, and 2nd, the characters who ARE able to jump that far are generally powerful enough to have access to some form of flight, either from an item, a friend, or a class ability.
