It would be good to add a "Recommends" or "Suggests" bash-completion to the lustre-client-utils and lustre-server-utils .deb packages (and also .rpm packages if that functionality exists today).

The "lctl get_param" command greatly benefits from having bash-completion to provide parameter names, and the other "lctl" and "lfs" commands like "lfs find" and also have completions for many of options, added in LU-12734 and LU-13225.

I don't want to Depend or Require that package, but it should be installed when possible. I was recently debugging on a client node that didn't have bash-completion installed, and it was more painful than I would like, so regular users should also benefit from these improvements.
