saveDeployment() before upload?

[hadley]

It's possible for bundling or uploading to fail, which means that you lose useful metadata (e.g. server and account)
Would it make sense to saveDeployment() prior to uploading? e.g.

saveDeployment(
  recordDir,
  target$appName,
  target$appTitle,
  target$username,
  target$account,
  accountDetails$server,
  serverInfo(target$server)$hostUrl,
  application$id,
  NULL, # previously bundle$id
  application$url,
  metadata
)

Would need to verify that you can still resume even when bundle$id is not set. (It doesn't look like deploymentTarget() ever uses bundle$id so maybe this is trivially true?)
