Its not an unpopular opinion.
Its actually quite more popular than you would think, just a minority of people who hate it.
As for me - I love it, its one of my most favorite aspects in both BotW and ToTk.
It makes you strategize with a limited inventory, instead of fighting head to head - you can do other stuff that you wouldnt do normally.
Besides when you progressed enough into the game, it really doesnt matter because you'll always be overflowed with weapons and other equipment.
If you were to ask me what the first thing that came to mind on why I rate BotW as my most favorite Zelda - its the weapon durability system.
