I'm less concerned with how they're implemented mechanically and more with the loss of narrative flair. I have a warlock character concept whose backstory and "inciting incident" for making their pact is essentially sacrificing something of themselves in exchange for knowledge of runes and writing, Odin-style, which I'd planned to represent through Eyes of the Rune Keeper - their entire reason for the making the pact (or at least one major aspect of it) was to gain the ability to read anything at any time.
Now that ability is locked behind a spell cast. One which (cast time, components, duration, and/or spell slot aside) is more versatile than simply being able to read any writing, to be sure, since it also covers spoken language, but is far less narratively evocative.
