AFAIK, the bash_completion script that is installed with the bash-completion
package merely is a latch script where all other software's completion routines
are sourced from '/etc/bash_completion.d'. You're free to source or not source
whatever you want from that directory without the latch script installed, since
it's your system/cpu time. The dependencies arising from that can be made
flexible by wrapping the source with a test -f each time. That would leave you
with a few additional lines in your ~/.bashrc or /etc/bash.bashrc, while
keeping out the bloated mess that is bash_completion.
See also, /etc/bash.bashrc line 23
