I think that it should work with the option `--command-fd=0`, which tells
gpg2
to get the commands from stdin. See this example:

for every unix guy that comes across gnupg.

If I am allowed to speculate, this happens because gnupg is a very ancient
program,
since the time of dinosaurs. However it is trying to become more modern
lately.
Another reason may be that it has tried to immitate closely OpenPGP.
