If the dotfiles are in the project dir, they'll be exposed of course. If not, perhaps a bind mount from ~/.config would work, but it could also unintentionally expose files on the host. It is possible to bind-mount individual files, so perhaps having a list of exposed config files / mappings could work.

The problem with this is that docker doesn't like it when not all mounts are found, so within a team it requires something more sophisticated.
