    I'm no expert here, but can you elaborate on why you removed these checks for the default value being in line with the min and max?
    
    I can only guess that this must be that way in case where the default parallelism is not within the bounds of the configured one. I'm wondering whether the `LongParameter` is used somewhere else were these bounds are expected to hold though.
