I don't know how viable or sane this actually is but one suggestion I
just made elsewhere which might help is to fix this at the dtc level by
having syntatic sugar which will do the parallel arrays trick that
people are currently using to write things out.  The user writes one
array with multiple types of data in it and the actual output is two or
more matched arrays each with a single type of data.

It would help legibility and wouldn't impact the parsers.
