There probably doesn't.  But neither should we avoid having an indication
and drive the staff lines to be continuous.

Squaring up the lines doesn't help.   Having the lines rounded works for
everything.  The rounded lines were proposed as a portential error when we
do stop/start at the same time.  I don't think they are an error.

Because in real engraving, all the outside corners are rounded.   It's a
characteristic of the tools used for engraving.

My point is only that this simultaneous start/stop should not be used as a
justification to eliminate rounding.

OK I see (although I think we got off topic there) so why not make stop\start, 
as an explicit command, rounded; and whatever you call 'end of barlines' that 
are either \break-ed or whatever LP does when it starts a 'new line' squared?
