Clearly, a rules interpretation that makes having a feat less useful than not having the feat is not a well-formed rules interpretation.

I think the insistence of ‘spell components’ made the game more complex than it needed to be. Unintentional snafus happen.
Errata to the Warcaster feat could fix the wording by simply saying, treat weapons or shields as spellcasting focuses.
Then the feat benefits everyone.
A Paladin, for example, could wield a sword in each hand, and the swords would substitute for the spellcasting focus. He is likewise able to perform any somatic component while holding these focuses.
