I disagree. Segregated witnesses, for example, doesn't solve all kinds
of malleability and is very useful in some practical cases by solving
all signature malleability.
As said, we don't want to eliminate all forms of malleability (for
example, replace by fee), although we may want to "address them" at
some level.
As you have said, wallets should be looking at scriptPubKeys, not
transaction ID, but that is orthogonal to SW, a normalized tx ID and
signature malleability.
