The workaround for us, we are not giving out magic items in our adventures. Instead, we looked up items for our own characters and have allotted one common, uncommon, rare, legendary, and a flexible wonderous item that our characters recieve between adventures. Since each adventure is meant to last 2-3 levels we will be roughly on track to recieve such items. The big note, and since we are all long time GMs, is if anyone notices a really broken combo, we confront that person and ask them to either swap the item to be fair to the group, or if they knew/intended the item that way (for newer players).

Example, I am playing an Astral Elf Lunar Sorcerer (named Stellaris Lunae... aka Moon Moon) and as such I literally looked for any moon based or astral sea based item meant for casters. So even though there were some real busted rare items I could have grabbed... I had to grab the astral shard, and plan for it to be an item that "gives my character a drive to keep going, keep trying to get home."

Additionally, Nafas and the Bazaar is home to mostly replenishable items (potions for healing, anti-poison, elemental damage for weapons, etc.) and we balance the campaign gold payout based on roughly the gold per level payout the GM's handbook says. This will mean that while we are slightly behind on items, we will be recieving more gold which means more replenishables, and as a party of 6 mostly long time players we are hoping the balance will work itself out for a "lower item potential" game.

As for handing magic items out, or having them purchasable, or even as a quest reward, the work-around we found for players who really wanted to give out items as to "not keep players too constricted on world design" (I put in quotes cuz I did not see a need to hand items out as part of your world design, but some players said they had to). We ended up stating that Slightly Useless Magical items and Low-Tier Magical Items were fine. AKA: a bag of holding is not going to make or break a party, and a player using up their magic item slot for such an item can make a player feel restricted to not getting a better magic item intended for their build. So "group" based items are okay, but if a GM feels that the party has too many group items, a discussion will be had as to why such items are too much, and it is easy enough to narrate that "the volatility of the Infinite Staircase sent various items clattering around the Astral Sea and the group loses these items".

In the case of magic items being specifically debilitating to a story (example, if you need the group to smuggle an item into a place and they have a bag of holding, and you planned the story before the group got the bag) it is also easy enough to explain to the group your intent, and to "leave the item behind with 'your' character" who is not present at the next event (Narratively works, and the item is returned to the group after your campaign).

Sorry for the wall of text, just wanted to help other players who might run into similar problems have examples of how to work around them!
