I think that this can also be gamed by a second, cooperating node that
sends payments through the channel to meet the rate and capture the fees
for the first. You can make this less likely by charging higher
transmission fees that make such an attack infeasible, and it's less
'damaging' than an immediate close in that there's still open capacity
available for some time, at least until the 'bogus' payments have drained
the capacity that you solicited in the first place.
