When are you going to add support for table, inline-table, table-row-group, table-column, table-column-group, table-header-group, table-footer-group, table-row, table-cell, and table-caption? These will make a lot of standards-compliant fluid-width site designs practical as they already work reasonably well everywhere else.
I hope the first NASA astronauts to get there won't have the option of landing in a Martian Walmarts parking lot and eating at the nearby Martian McDonalds, but some days I do have my doubts.
They never have before, and in fact the FDA would actually consider the existence of such a backdoor a risk that'd have to be evaluated as part of the process.
As someone who has released network-capable medical products professionally, I can say that the FDA has already been requiring companies to provide all this information anyway. All that's new here is that there's now a final guidance in place that means less guesswork in trying to determine exactly what information they care about and what format to provide it in.
