Close, but not quite. The current implementation of LN requires a malleability fix (which it has accomplished by means of segwit). However, other second-layer, payment channel implementations have been designed and scenarioed which do not require such a malleability fix.
BCH has for some time been discussing whether or not to adopt a malleability fix. And if so, whether segwit or some other mechanism (several have been scenarioed) would be the proper mechanism to adopt.
Agreed. While it is a longer-term issue, there are much more pressing things upon which to focus.
