The only problem (if its a problem) with Dex is that it doesn't trigger the yeast to release invertase, this is a personal theory but I believe the yeasts response to sucrose is fundamentally different to how it handles Maltose or Glucose.
A part of the cidery taste ascribed to using sugar in home brew is I believe down to the massive amount of invertase yeast pumps into a high sugar environment, I think there are other flavour effects to - lets face it yeast can do some pretty off the wall things under different conditions.
In brewing most things aren't either/or but a series of trade-offs and although there can be obvious downsides to using a lot of sugar, some used the right way in a particular style of beer and with a yeast selected to respond in a particular way to sugar can be a benefit.
Personally I like to add my sugar as a solution when the wort has peeled off about the gravity that I'm adding, if that makes sense. The lower OG means less stress on the yeast and as most home brewers aren't usually pitching enough yeast, the lower the stress on the yeast the better. So the sugar is going in on day 2-3, I find this works really well and helps get closer to the authentic Belgian flavours I'm looking for.
