I'm with you there. BUT. Python programs use configuration files. And
Python programs provide daemons. Its entirely reasonable and expected
within the context of a given program that 'sudo make install' or
'sudo setup.py install' or <...> any number of variations should make
the program be usable by all users of the system that its installing
I'm going to presume we agree on that in the rest my reply. You may
want to stop here if we don't agree about that.

Unless-and-until distributions provide a standard home-dir scoped
place to install bash completion scripts, developers and users
installing from python packaging are going to expect that the
completion scripts in the software they are installing get installed.
Expecting every user to home-roll a workaround multiplies the overall
cost by the number of users. So I can imagine three routes...
- teach the thing being installed to install completion scripts into
the existing right place(s)
- define a new place thats homedir and virtualenv friendly and teach
the thing installing them to install there.
- punt and do nothing
There's a big chunk of complexity hidden in my second point there. And
even if we do it we still need to get it onto our dev machines: Mac OS
X, various versions of Ubuntu, Fedora, RHEL and Suse. So I don't think
it makes a lot of sense to bank on getting that right-and-out-there
before we look at the user experience directly.

Since the entire job of the dh-* script ecosystem is to automate
repeated patterns without making individual developers figure things
out, I find 'miserable' comes across as a massive exaggeration. Surely
its a single one-off dh script to create to handle bash completion
scripts and move them into the right place, and you are done?
