Node v14 is ~EOL so we won't expect this to work going forward. We should revisit whether or not we should block users from creating function apps with this runtime.

This actually doesn't have anything to do with EOL dates. The old programming model (v3) is supported on Node.js v14+ and the new programming model (v4) is supported on Node.js v18+ as documented here. The new model has never and will never work on Node 14. The old model should continue to work regardless of the EOL date, although customers are required to upgrade before they receive customer support
