The Constitution disagrees with you on that:
Options which the voters rank above the default option are options
they find acceptable. Options ranked below the default options are
options they find unacceptable.
A less disputed example makes it more clear where that does make sense:
3 of the 6 TC votes (Steve, Colin, Russ) voted all sysvinit options
below FD since they do not consider sysvinit acceptable as default
init system for jessie.
I doubt anyone thinks that further discussion is needed for sysvinit,
but some TC members do sincerely not consider it an acceptable option.

No TC member ranked FD on second place, and all 6 votes stated that
both D and U are acceptable.

Under the assumption that both Keith and Bdale rank DT above FD.

DT beating FD only 5:3 would be a sincere expression of 3 TC members
that they do not find T acceptable.
I'd actually call it a bug in the voting system that the casting vote
might decide between an option that 3 TC members do not find acceptable,
and an option that is unanimously considered acceptable. 
But there is no perfect voting system that handles all possible cases

That would enforce extreme tactical voting in TC votes for everyone
wanting to express something like "sysvinit is not acceptable":
A TC member would have to initially vote "yes" to FD, and only switch
it to "no" when the remaining votes make it clear that the option he
considers unacceptable cannot win.
Or wait with his vote until the other votes make it clear whether he
should vote "yes" or "no" for FD.
 if both Keith and Bdale would rank DL above FD
