You should check with specific capabilities rather than with levels.
Like edit_posts, edit_options. Then just specify in your plugin docs
what capability users need to do certain things (or give a plugin
setting where the needed capability is defined from a list).

People who have custom roles will be confused by any use of levels,
the level values are deprecated reverse-compatibility for the old
system from before roles and capabilities were added.
