I think you're overestimating the hazard. Or, at least, the risk that
it can be encountered accidentally.
It's not like Categories haven't been used in 'serious' software,
after all.
In the 90s, NeXTSTEP and Objective-C (with Categories) were safe
enough to be used for investment bank trading systems (derivatives,
fixed income trading, that kind of thing) that safely handled vast
numbers of high-value transactions (hundreds of millions of dollars
each and up).
It's possible to conceive of theoretical situations in which things
could go badly pear-shaped due to a Category. In practice, because of
the ways people typically use Categories, it just hasn't been that
big of an issue.
