There was a problem hiding this comment.
Should this instead be replaced by norm_le_one_of_isometry?
There was a problem hiding this comment.
There is norm_noninc_of_isometry that combined with norm_noninc_iff_norm_le_one gives what you want.
It depends if we prefer to state lemmas about f.norm_noninc or about ∥f∥ ≤ 1 (or both of course).

`bound_by f C` is the same as `∥f∥ ≤ C` and it is therefore useless now that we have `∥f∥`.
