[LES:] Are you claiming this because you know this to be true - or are you just 
speculating that an implementation "might" do this?

If there is an implementation doing this (i.e., sending max-metric for prefixes 
in conjunction with setting the OL bit) I would like to know - and I would like 
to know why such an implementation does this.

I am familiar with implementations that may set max-link-metric in conjunction 
with setting the OL bit.
I am also familiar with implementations that withdraw advertisements of 
prefixes in conjunction with setting the OL bit (oftentimes under control of a 
configuration option).
But I am not aware of implementations that send prefix advertisements with max 
metric in conjunction with setting the OL bit. Doing so seems rather odd and 
not very useful. If an implementation wants to indicate that traffic for that 
destination should not be sent to that router, it would normally simply stop 
advertising the prefix.
(The OL bit, of course, would keep traffic from transiting the router.)
