As Greg mentions, this is the same on other Unix systems too. Now, as you mention, this has the drawback that you can't eject a disk while you are at that folder. This is why [traditional] daemons chdir to / as part of the usual procedure of going into background. However, there may be cases where you want to keep that reference open. For instance, the folder could be on an autofs mount, or you could be working on a deleted folder. The simpler use case for needing this however, would be a rename in the folder path. Suppose you were working on /home/danyel/myfiles/ 2017bugrports/bash/cwdspoof Then you notice that there is a typo in the path, and should be named "bugreports". You will find that you can externally rename that folder with no ill-effects to the running bash. $PWD will be wrong, but you can continue working in bash and launching programs. Whereas with cwdspoof trying to use that console would fail. There's also the efficiency argument about needing to traverse the folder path before every command, which won't be that fast when network is involved, or even a simple cdrom (although in that case it could/should have been cached by the kernel).
