Selecting a random one of theses reports...
Could you create parent / child relationships between all these requests? It will make it easier to work with and integrate if you do. Thanks!

Will do, but just to clarify the "why". As a new contributor I thought (perhaps wrongly ?) that the reviewer community would prefer if I kept my individual differential minimal so they were easy for you to review and reason over.

But so I know for the future, would you prefer me to create one differential that covers multiple files e.g. in this case, I could have, for example, created "shell script modernization/best practice" and lumped all the differentials in there, since they are effectively all very similar (double-quoting etc.). Or do you prefer the parent/child linking ?

And if you prefer the parent/child, e.g in this instance where there is no clear "parent", do I just pick one at random ?
