Well you contradict yourself here :). Yes, I fully anticipate wallets attempting to market themselves as "quantum secure". I do not anticipate most "mainstream wallets" will care at all - if I search the app store right now for "bitcoin wallet" I get bitcoin.com, coinbase, and trust wallet as the top three - all of which have objective histories of taking 5-10 years to adopt incredibly basic bitcoin technologies and never adopting best practices or marginally more complicated technologies. And, indeed, as you point out, a large subset of the bitcoin community is unlikely to care until the threat is imminent, at which point migration is much too late. It doesn't matter if some set of people migrate, if a large number haven't its the same net impact.
