Cheesecloth of holding is so going to be an item in my next campaign.
One home‑brew rule (more an ignored line than a written rule, as I rarely insert magic items in my game that are exactly like those in the DMG) is to drop the line about one action to retrieve. I just keep it vague. This is something that I've always found more fun for the players and DM to determine what makes sense in the moment and what is fun. The closest I've ever come to have a mechanic for retrieval is to have the player make a dexterity or perception roll to see how quickly they can pull something out of it with the DC set by how much and what kind of stuff is in it. If the person trying to retrieve an item fails the first round, I would drop the DC the next round, and so on.
Replicating the "I really need to find my garlic, the vampire is getting really close to me... drat, that's a mosquito repellent". It can either be a tense moment or a Scooby-Doo moment
