For all the talks about finding alternative resources, I ended up at Wanikani through my own research as well, and joined as it is the best one I found. If you know of better ones, I’d really appreciate if you could share them here.
Otherwise skipping radicals and kanjis doesn’t take away anything from Wanikani. If WK fear the skip feature may be used inadvertently, it can be buried under submenus and guarded by a warning and confirmation. It wouldn’t affect anyone who want to use WK as they do now, nor would it affect newcomers who are not introduced to it. They are strict improvements to let WK cover a bit broader demand. WK is designed for Kanji memorization, but its SRS engine is generally good for any memorization, and a well guarded skip feature can let people take advantage of it more efficiently.
As all have pointed out, the feature is not necessary, and the beneficiaries are few, so as a fellow software engineerer I understand it might not be worth developer time. But coming from Linux where things are configurable to a fault, I honestly regard “WK is not for those who want to skip” a lack of imagination.
