I really like Wagos. I don't think a cover or tape is necessary though. I use them at work (industrial) and at home and never had one accidentally open.
I believe they are very popular in Europe too and never seen a sleeve or heard of needing tape. I imagine they've gotten enough use by now to prove out if it's necessary.
