Details
There are some open questions about the interaction between sccache and incremental (https://github.com/mozilla/sccache/issues/236), but in the case we're distributing compilation we may end up better off distributing the full compile rather than disabling distribution and doing a local incremental compilation.
We'll want to test this out once we get a decently sized cluster stood up in one of the offices.

Do we want to detect when RUSTC_WRAPPER generally is using sccache, and disable incremental compilation in that case, too? Or will that just naturally fall out of this work?

Not sure. According to https://github.com/mozilla/sccache/issues/399#issuecomment-479919479 path-based crates wont be cached in this case, but crates from crates.io will, which seems like a possibly valid configuration. More measurement is necessary.

This was done in bug 1576030 (for any use of sccache, covering out purposes here).
