Brane, you already persuaded me at the SVN summit that Subversion's
current branching model should be buried as an implementation detail.
In fact, the branching model that I use in cvs2svn separates the line of
development namespace from the file namespace just as you advocate
because (1) it is simpler to implement; (2) it is a better match to CVS
branches and tags; and (3) it is a better match to git's model, which is
the other output SCM that we currently support. But given that the
Subversion world isn't changing soon, a simple hack like this (almost
zero work) might ease the pain a little bit. And in the unlikely case
that SVN ever changes its branching model, something like the suggested
property could help with forwards and backwards compatibility.

True, but there are far fewer project lines of development than merges,
and only one level of any SVN path in a conventionally-structured SVN
repository should ever have this property. The most common questions
would be: what line of development does this file belong to? (traverse
path towards root until a project root directory is found) and what is
the complete list of lines of development in this repository?
(breadth-first tree walk starting at root and pruning whenever a project
root is found).
I'm not saying that edifices should be built on top of a hack like this;
just that it would be a very easy way to keep track of project roots in
today's SVN in a not-so-terribly-inaccessible form.
