As already stated it depends on your setup, and where and how you dive. If you do deeper dives, with a heavy set, using a thick wetsuit (double 7mm), then ditchable weight will be very necessary, because at the heaviest (beginning of the dive at the deepest part) you probably won't be able to swim this weight up.
If you dive in the tropics with a alu single tank, you probably don't need any ditchable weight because you're not taking much weight down with you (me typically about 3kg/6lbs)
I dive a "balanced rig", meaning a rig I can swim up when it's the heaviest and can keep down when it's the lightest. So in all normal situations the only variance will be the weight of the gas I'm breathing. This difference in weight is most of the time manageable between beginning and end of the dive.
However having said that... I do dive a small weight belt (2KG/4lbs) to dump. It's not as easy to dump as my previous dumpable weight (battery pack), because it's below my crotch strap of the BP/Wing but I'm sure I'll be able to dump it if necessary.
So it all depends.
