I think that's okay: company skips this capf because it has another 
completion source configured by default (which also "will always popup 
the candidate when I input English charectors").

Corfu doesn't and follows the current CAPF configuration. In which case 
showing the ispell results seems reasonable. Though of course some might 
not like that. I don't know whether that merits a new user option.
