My institution has only recently started deploying and supporting our DoOO initiative, so my observations are unavoidably naive. We're also feeling a bit like kids in a candy store at the moment, so I've not reflected much on aspects of our digital scholarship that may be underserved.
That stated, I can think of a couple things to contribute to the discussion. First, I have some concerns about the long-term institutional preservation of the projects and data generated as faculty and student DoOO-based endeavors. I'm not sure, from an institutional memory stance, how much we can presently commit to curating the scholarly work that DoOO enables. I'm not even sure what sorts of tools might be available at the institutional level to allow us to do it. I'm reminded of my long-ago /~yourname (aka tilde sites) web area provided to me. While I was able to take that work with me with ftp and floppy disks, I am nearly certain that there was no institutional archival policy in place for all that student work, and I think it's kinda sad. Speaking as a technologist and a librarian, my hope is that DoOO can factor nicely into our institutional repository, and that student and faculty DoOO-based work undertaken now can, somehow, inform the scholarship of 100 years from now, like our analog archives.
Another thing that I'm trying to think through concerns the disciplinary alignments of the tools presented in the cpanel. I'm slowly working through everything there but I'm sensitive to its skewing toward the arts and humanities. The social sciences don't appear to make out as well, and still fewer returns for the sciences. I recognize that this statement may be loaded and may rile some folks -- so I'm happy to retract it if proven wrong, or once I've had more time to really look through, install, and evaluate from a pedagogical orientation, all that cpanel offers.
My final qualification is to point out that cpanel shortcomings are not entirely DoOO shortcomings. Take for instance a scholarly desire to do some web mapping stuff. While PostgreSQL/PostGIS aren't listed on cpanel, that doesn't mean I couldn't install them through the shell (theoretically speaking; I haven't tried this yet but plan to do it). So yeah, while I noted a couple areas of concern above, I also think that the full utility and power of DoOO is sometimes understated, too.
