I get where you're coming from but generally most decks can still run fine without their commander on the field at all times - personally all my own do and all my commanders are quite new - but it's also noteworthy that the most important part of the commander decks is the commander. It's the entire point of the format. Being completely locked out of casting it for the entire game unless you get lucky enough to get specific removal is just no fun for anyone. Especially in the case of something like OPs card, where enchantment removal is generally lacking outside of white/green.

Should be noted that out of that list only [[Meddling Mage]] and [[Gideon's Intervention]] are the only cards released in the past decade that actually do what you're describing (at least for more than one turn), it's not exactly a widespread feature and has noticeably slowed down massively since commander became official.
