Your pathological example is not how we encourage these header arguments
to be used. Their intended purpose is serving as arguments, not to
complete the cmdline. Anything else is implementation details we may or
may not change in future. It need not be reflected in the header
argument names. So, I stand on the :*-args names.

Max, I believe that we discussed this. This problem has nothing to do
with introducing new header arguments. It is just a question of how we
pass these header arguments to scripts. Your concerns must not stop Matt
from working on the proposed patch.

I fail to see how this relates to new header arguments.

This is also out of scope of the discussed header arguments. Using
custom interpreter (flapak-spawn ... bash instead of default bash) has
nothing to do with script/interpreter arguments. We may (and should)
discuss that question separately.

Let's not raise all the possible related concerns at once, unless they
cannot be resolved in future because of the discussed patch. Otherwise,
it is almost impossible to make _incremental_ progress.
