I think it's a thing where doing it once or twice, with a name that actually makes sense and is for something that genuinely matters to the story is generally fine. The Reapers? Cool, functional name for the omnicidal robots. Halo? Perfect for a giant space donut with religious overtones.
It gets a lot less interesting when it's for every last rando bit of plot junk you need to pick up. And one of them is probably like the Conduit or the Catalyst, which is just dull at this point because dear me have I brought a lot of Catalysts to a lot of Conduits.
I've always liked silly fantasy names for stuff. Done right and you can get some world building or sense of character in there. Done badly, at least it can be slightly weird.
