If anything, a claim of "it is certifiable but we are not going to certify it" would raise serious red flags.  A statement of "it is in the process of being certified" would be in only marginally better, unless that particular team of engineers/certification-folks, under that particular company, under that particular management, has a track record of certifying similar products, in which case I would be willing to give it much more credence.

Standard disclaimers about my involvement with Chelton Flight Systems applies.
