Yes, it seems a likely response. The underlying assumption is
that people expect the Sun to be roughly overhead at noon to
within a tolerance of about an hour.

Leaping timezones would be tenable if they all leapt at the same
time. However, I think we agree that that won't happen.
Currently the main chaotic element of timezones is concerned with
the start and end date of DST. The chaos is restricted to two
periods, sometime in autumn and spring, and it only amounts to one
hour to and fro.
Leaping timezones, each "at their own pace", can only add an extra
level of chaos, one that will eventually lead to multi-hour offsets
that continue to grow over time.
