Hey, good to see you here! I am not an expert in these matters, but
since it seemed like an interesting problem, a couple of inane questions
for you -

Do you have reason to think Haiku Tracker works that way, execute
permission allows drop? It's easy to find the code where it uses
permissions to make the app vs. file distinction you go on to
complain about, but can't see where it uses permissions to decide
drop behavior, and empirically it doesn't look like that works
(though I may not have set all the right attributes?)

You mean, not needed in the particular case of /bin/sh, because that's
xicon's default? You'd need the "shebang" line if it was Ruby, right?
Or an attribute?
