This sounds like a non-issue in what is essentially a single player game with no PVP. I mean... maybe just don't do it rather than asking them to break apart their inventory system to counter a fairly unintuitive way to get advantage.
I would say the changes I suggested shouldn't be particularly complicated to implement.
I don't think it's a non-issue. Maybe some people do, but I don't want an experience where I have to decide what should and shouldn't be allowed. Primarily, the game should avoid having broken mechanics. If devs are unable to do that, then sure, maybe it's better to create your own custom rules for your playthrough to make it more enjoyable. Also, changing equipment mid fight is something that could be balanced and have a cost. "Just don't do it" isn't really a solution. I want it to have a proper implementation that makes sense.
People complain about rest system not being good, since you can long rest almost anywhere. This greatly affects the balance of warlocks and other spellcasters in particular. It makes the game less exciting when you can long rest after every encounter. Now you don't have to do that, you can choose to long rest less frequently. Does that mean it's a non-issue? No. Devs should absolutely do something about.
Similarly, let's say the weapon set switching trick. One press of a button and you can switch to sword/shield after shooting with a bow. The game allows it. It's a mechanic. It's easy to do. Why wouldn't you do it? It's not a great experience to play a game find mechanics that make you go "yeah this is dumb" and have to decide if you should use it or not.
I'm also not saying this is a deal breaker and I can't enjoy the game. This is EA and they are asking for feedback. I find that this is something that they could change to improve the game. If the devs don't care, whatever, but why are you opposed to suggesting improvements?
