There used to be a prefix for 10 000, namely, myria. One can see it
listed in the U.S.'s Metric Act of 1866.

It is all well and good for people to have their preferences for use or
nonuse, but those are personal opinions which a person my reflect in his
or her usage of the SI. The authority for the legitimacy of a prefix is
the SI brochure, however. It says nothing about some prefixes being less
preferable than others.
