The naming looks funny, when you are mixing camelCase and
underscore_split in the same name. Also, do we really need this
boolean? How many test files would have to change if we change all
existing outputs to always include type='isa-serial', where the field is
optional only on input; vs. your approach of using this bool to omit the
field on output if the user did not specify it on input?
Overall it looks reasonable, but depending on the answer to whether we
should just always output type='isa-serial', you may have a v2 to submit.
