You can't know how large the actual transaction file (assuming you're
using FSFS) will be in the repository until the transaction has been
committed.
There is compression done in the repository, in addition to other
tricks used to reduce space. The "abstract view" you were referred to
is important to understanding how Subversion stores things, so please
don't dismiss it.
What happens if you have a legitimate case for storing something
larger than your arbitrary size limit in the future?
