I am not familiar with this format. Overall LGTM. I just have a few suggestions.

Maybe for a new feature: call dense2csr(A, CSR)?

Yes, it could embed the call in just one. Actually I think it might be interesting to have a single interface to automatically detect the input and output matrices such as to internally apply the conversions having a unified API. Haven't thought it through yet though.

It could be something like:

 subroutine dense2sparse_${s1}$(dense,sparse)
 ${t1},ドル intent(in) :: dense(:,:)
 class(base_${s1}$_type), intent(out) :: sparse
 select type (sparse)
 type is (COO_${s1}$_type)
 type is (...)
 end subroutine
