Summary: This at least saves compile time. I also encountered a case where ephemeral values affect whether other variables are promoted, causing performance issues. It may be a bug in LSR, but I didn't manage to reduce it yet. Anyhow, I believe it's in general not worth considering ephemeral values in LSR.
