Exactly. I recently started to write some LEAN which uses a ton of Unicode characters and I still use JetBrains Mono with ligatures on. ≠ is 1 unit wide but != is 2 units wide, so it's not that confusing as one might think.
Besides, if someone insists, it's also possible to make a language-specific setting in the editor to disable ligatures in those languages :)
