I think the general idea is that you use a bag of holding, or Heward's Haversack, or some other self-crafted item that enables you to easily call desired objects to hand while making sure those objects don't count against your encumbrance.
(Also, encumbrance is a tedious rule to have to bring to bear to rein a character in.)
I don't mind that sort of game but would never use D&D for it.
This is why 3E has never really appealed to me. It's a mixture of gonzo (eg hit points) and gritty (eg skill rules) that strikes me as inherently unstable for a wide range of approaches. And recurring threads like these don't dissuade me from that impression!
Encumbrance may very well be tedious, but ignoring it is still a factor in giving a class which is already viewed as being too powerful (wizard) an advantage over a class which is already viewed as not good enough. There are a lot of other issues which often get ignored in 3rd too. That doesn't change that many of more mundane classes don't keep pace, but it does make the problem worse than it already is.
At this point in time, I don't believe I'd use D&D for a gritty game either. However, I wasn't aware of what other options had to offer during times when I was trying to do so and became frustrated. I think there are times when D&D presents itself as something it isn't. As a matter of fact, I've said in a few threads elsewhere that I believe one of the biggest problems 4E faced was that what the game actually was in play didn't match up very well with how it was advertised and marketed.
To the last point, I can only say that I agree. I think 3rd does a great job of showcasing a wide variety of playstyles, but it doesn't always do a good job of supporting them. Sometimes it can fake it well enough that you don't notice if you're not familiar with what other options are available. Still, I do believe 3rd introduced a lot of concepts which were good for the brand overall, and I do still believe it help to push a lot of design ideals forward. At the time, I loved it, but I don't believe I could ever go back to it more than to just dabble in it. Now days, I mostly use my 3rd Edition library as source material from which to convert things to the games I play now. The fluff is still useful.
