I do think there might be some complications, though. I think we may
build commit graphs by default these days during "gc" and even
incrementally after "fetch". If we warned when the graphs are disabled,
it basically means that every command in a repo with replace refs would
issue the warning.

yeah, i thought about that, too ...

it would be easy enough to squelch the warning by manually disabling 
writing or using the graph. the downside is that if the root cause gets 
fixed, the user would be still missing out (unless they read the 
changelog and remembered to reconfigure all affected repos).

one could make it an advisory message which can be explictly squelched.
