While what you say is of course technically true, I suspect most editors
respect the property. VSS and PVCS among others have relied on this
read-only behavior for more than a decade. I have never seen editors have
a problem with it. Some even turn on their own overlays when it is set.

I think your argument is that you want TSVN to check for the needs-lock
property and decorate when it is present? I can understand that
sentiment, but I liken it to wanting to know if someone else has the file
locked. That would be great to know, but at too high a cost. There is no
way that TSVN can retrieve that property on every file, and provide good
performance. The Subversion devs decided to follow the convention that
most other locking tools use, which is to use the read-only attribute as a
hint to the user and their tools that a lock should be obtained before
editing the file. I do not think there is anything else that TSVN can or
should do.
