"I reckon the timezone fudge is workable for rate errors as large as 1e-5, which would imply a timezone change every 11 years."
The resulting discussion posits the very situation you're spurning.
More to the point the entire notion of playing musical chairs with the worldwide timezone system ignores the perpetual rate error that matters for astronomical and aerospace applications. It happens to also not be realistic to expect civilians to shift to UTC+(N+1) every decade but more importantly this would do absolutely nothing to address the technical requirements. It is purely a rhetorical gimmick to justify redefining UTC without having a plan for mitigating the resulting impacts.
