This may not be a popular opinion, but if you need to dedicate a single FTE to your webpack configuration, something sounds amiss. Alternatively, if that's your engineers only skill (building webpack configs), that also sounds quite suspect.

In most projects, the webpack configs are not edited often, maybe unless you're upgrading a new major version of Webpack itself.

They're not edited often because they're hard to edit. Many times webpack issues just get deferred or ignored because no one has the time to investigate them.
