Although removing these dotfiles gave the repository a clean feeling, it
made it significantly harder to resume using a certain window manager or
other tool at any time.
Instead of removing dotfiles entirely, it's enough to simply not install
the programs you don't want to use, or even install them but not open
them.
It turns out that placing similar config files (i.e. bspwm-related) in
the same directory is not the way to go about handling dotfiles since
each config file (or dotfile) *should* manipulate only a single program.
This was not the case back when I used urxvt (which would require the
old method of .Xresources), but now that I understand more about how
*modern* dotfiles work (with $XDG_CONFIG_HOME), separating dotfiles by
program became the obvious choice.
