I mean it is possible to define "bad", but it would be something like "the common actions take too many keypresses". And that's about it, which isn't really a problem KiCad has anyway.

Even default keybindings are very personal. Some prefer to focus most of the common ones in one place (say around the qwer/asdf/zxcv cluster) so you don't need to move hand much, while others would rather go by easier to remember names and have [M]ove and [D]rag. I guess you can still define the "bad" here by neither intuitive nor convenient, which is to say "LTSpice", but most programs are not that.
