LN doesnt have a blockchain. there is no need of a softfork.
LN is already failing in the respect of 'hop/routing' and so they are moving more to the 'hub/spoke' model.

the initial overhype/promise of LN was
'just lock up your funds into A channel(singular) and be able to send instant unlimited payments to anyone'

now its more like
'divide up and lock up your funds into channels(plural) with the main retailers you regularly spend with to send them instant unsettled value'
