Personally confirmations have helped me in the past. There have been one too many times on my lap top even where I've done the wrong thing (eg: using the wrong item on a pet) and that pop up has really saved a lot of mishaps. Before the confirmation for using things on pets was implemented, I wound up accidentally turning my poor Eyebright into a Darkonite and he was an Angelic Kumos. The popup confirmation alerts really help prevent accidents from happening. The confirmations may not be loved by all, but I can tell you that if you wind up in a situation where you're using a valuable item on a pet or somewhere else and you use it on the wrong pet or choose the wrong thing or whatever, you'll be grateful that the confirmations DO exist! XD
But yeah, the delete option for the loyalty box really shouldn't even exist lol! WHY on Earth would someone want to delete this thing?!? XD I am all for the removal of that option, too! Delete the Delete option XP
Yes. This has happened to me, too. Not necessarily on my laptop but on my phone when using Subeta...in a stationary location. My browser has jumped many times and so many times I've been messed up and have done things I don't want to do. This could very well be a case for others, too. Browsers can jump and glitch and issues can arise and then what? You're stuck with an item you don't want.
But then again, the transformable option might help with this...might. It'd be worth a shot.

I'm always for confirmations because I am hilariously uncoordinated and it's only a matter of time before I do something unbearably stupid because my hands and my brain don't agree.
I'm 80% sure the reason there's no transformable option is because pet slot totems have been awarded in the past for site goals-- and if those were never used, users could transform those into something else from the LB when that wasn't the reward intended (otherwise, they'd have just given us the box).
I wouldn't mind there being a pop-up confirmation, as long as it actually said "are you sure you want the -thing you clicked on-" instead of just "Are you sure?" which doesn't help anyone. I won't die without it, but I wouldn't mind seeing it happen.
