I think the issue is not really whether HAVE_DOT=yes is good or not
in general, but whether this is an issue that should be decided on a
per package basis or not.

Packages using doxygen usually have a file in which they put options
like this. From 57 packages I checked, 9 of them deliberately set the
option to yes. The upstream default is no, so this means the other 48
(sort of) deliberately decided not to use dot (by not overriding the
variable from its upstream default).

But we are currently overriding all of them.

Thanks.
