Yes.

The issue here is that the message is bogus.  The VCS that is used
does not require "C-x v v" to make the file writable, because the file
is already writable under bzr.  The _buffer_ is made read-only by
"C-h H", but the file is not.  Perhaps VC sees that the file is under
VCS control and the buffer is read-only, and erroneously deduces that
the VC backend is some VCS of the locking variety.  But that is false.

I think VC should not display this message if the backend is not a
locking VCS.
