Reading your answer I thought (seemingly unrelatedly) about yet another possibility but still am not sure whether to include it in the question. You see, in principle this might not even be a group - rather, having in mind highly connective covers of Lie groups, one might think of maps "linear up to homotopy", together with chosen such "linearizing homotopies". | |
