flicking the question around, how much will it cost operators to upgrade
these boxes, and are they prepared to make this investment in order to fix
a problem which for the most part has a minimal impact on their networks
because 50% of web sites don't accept fragments anyway.

These devices are ubiquitous on the internet.  The IETF should ignore them
at their peril.  As Joel says, they're not the only box with problems, but
they are one of the problem contributors in the core.
