I think that relies on a number of assumptions. I've had complaints about this
from multi-branch/multi-library users of Koha, but you could have the following
scenario in a single branch:

1. Library technician transcribes book and sends it to cataloguer for subjects
and classification and leaves the catalogue editor open
2. Librarian starts opens record on screen and does their work
3. Library technician notices a typo in the existing editor tab on their
browser. Saves it and accidentally erases the librarian's work

I don't think DBIx::Class is database lock friendly at all. 

In general, locking does seem difficult, as how would you know if a page was
abandoned or some other related scenario. 

I suppose that's where session timeouts would come in, but that could also be
problematic.
