The failure here seems to stem from an upgrade to @apollo/utils.keyvaluecache in v4.0.0 which dropped Node.js 18 support. This then has been taken in by this PR which transitively dropped Node.js 18 support. I'm doing a v4 -> v5 upgrade of a standalone @apollo/gateway server. I'm having trouble as some of our static analysis analysis says there is a breaking change going from v4 to v5 because @apollo/gateway has a breaking change on the interface library from @apollo/server v5. As far as I can see there has been no functional change.

Is there a plan to drop Node.js 18 support from @apollo/gateway which will unblock this PR and align the dependencies?
