the developers of Start11 are making a conscious and deliberate effort to actually ensure that both programs could be used concurrently without a loss of functionality in Start11.
Or a deliberate effort to try to protect users such as yourself from tanking your OS totally.
Perhaps you can elucidate as to what efforts have been made on the part of StartAllBack for co-existing "nicely" with Start 11.
All support processes are intended to resolve issues of OS instability as and when reported by the user.
You as a user set up your system with acceptable[to you] options with both programs not disabling/conflicting with what you chose.
I don't think it's the job of Stardock Support to hold your hand to enable you to repeat it.
Policy has always been 'either/or', not both.
