If I remember accurately this is already true for current Poon-Dryja channels 
in BOLT 1.0, so at least it is not a degradation of performance.
It does make this modified form of Decker-Russell-Osuntokun much less 
attractive for use with DLC as the Fulgurite effort would like, but the 
Fulgurite effort already mitigates this by splitting a channel into two 
sub-channels (one for high-activity LN payments, one for rare-activity DLC 
bets) anyway.
