I'd actually argue that this shouldn't be done: data is sometimes reused
amongst multiple different test scripts, and when looking for data to
reuse its easier to spot it in a single directory compared to searching
through multiple directories.

I don't think that will be an issue. The automated process would read
the test script and see what input files it uses, copying those into the
archive. So, just be sure to standardise on using test_input_file() to
make that possible.
That said, I wouldn't mind especially either way. Just don't do it now,
since test script names (and therefore the name of the directory you'd
want to store the input files in) might all change.
In fact we can imagine that we have a test script t/BioZombieKitten.t
which stores its test data in t/data/BioZombieKitten/input.file but the
script gets the path to this file by:
my $input_file = test_input_file('input.file');
test_input_file() is then implemented to look for the file in the subdir
of data corresponding to the script name if we're dealing with the
900-modules-in-a-package checkout-type situation, but just in t/data if
we're in the one-module-in-a-package situation.
In any case, things will be most flexible if you drop files directly
into t/data for now and reference them without any subdirs in the call
