Feature request: Is there a way to get actual validation?

Running sam validate and/or cfn-lint both throw no errors.

But deploying throws an error about something simple like,'SecondsUntilPause must be between 300
and 86400 seconds'.

Is there not a way to check things like this before deployment and then having to go an manually delete the entire stack because it enters ROLLBACK_COMPLETE and becomes essentially useless?

Start by reproducing the example with `sam validate` and `cfn-lint`, then compare their results with the deployment error for `SecondsUntilPause`. Done means validation reports this invalid range before deployment and prevents the stack from entering ROLLBACK_COMPLETE; no source files or tests are named in the issue.
