The yum backend can do a remove with depremoval, but it is not made 
available in pkcon because it is to dangerous.
You will not see a list of what is getting remove, before the removal start.
I see pkcon as a testing tool for packagekit, not a replacement for 
native package tool.

yum remove gimp

should do there thing you want.
