And, I forgot to mention, the other important aspect here is reproducibility. Create/modify a code, put it in a signed container (like Singularity), use it, write the paper. Five years later the machine on which it ran is gone, your new grad student wants to re-run some data. Easy, because it is in a container just run it on any system that supports your containers. No need to ask a kindly sysadmin to help you track down libraries, compile, and run an older code.
