Agreed with the comment to get rid of it as a junk item, or add flavour text to the effect of "Known to be a legendary item to many adventurers, of no use to you."
Rope has strong connotations in D&D as being extremely useful, I get the wink and nod to it but when the game has a lot of interactions, having an item with the reputation of rope in D&D but never actually useable isn't ideal.
Been thinking about this more lately, and I realized that it should NOT be all that difficult to just code rope to be an item that provides either the effects of the feather fall spell (like when a spellcaster casts it, where it effects everybody), OR an upcast fly spell that effects the entire party. Those mechanics are built into the game, and essentially, mechanically speaking, that's exactly what rope should accomplish in any given situation. Either get you up somewhere you couldn't otherwise get, or help you get down somewhere without taking fall damage. Adding that coding to the mundane item "rope," would make it just as useful in BG3 as it is at the tabletop, and seems like it shouldn't be that hard to implement.
