Should there be CBLAS interfaces to CSROT and ZDROT ?

[martin-frbg]

In OpenMathLib/OpenBLAS#3063 it was noticed that CBLAS interfaces for CSROT and ZDROT are/were missing from OpenBLAS' cblas.h .
Given that the BLAS versions of these functions appear to have been in the reference implementation since at least 3.2.1 (the oldest I appear to have available in my lair, which also predates inclusion of the CBLAS), I wonder if this is an oversight here as well, or was it a conscious decision ? I do note that MKL and Accelerate both carry the CBLAS interfaces, and Atlas added them sometime in 2008 with a mailing list comment to the effect that they were non-standard.
EDIT: same for cblas_crotg and cblas_zrotg
