Who is this magic user with only one CC algorithm enabled in their kernel? I want to know who this dude is? I don't think it's going to help much since people will have I think at least two algorithms compiled into nearly everyone's tree. Distributions will enable everything. Google is going to have at least two algorithms enabled. etc. etc. etc. Getting rid of indirect calls is a fine goal, but the precondition you are mentioning to achieve this doesn't seem practical at all.
