That, in turn, results in more instability and insecurity for the PKI ecosystem and penalizes non-participants of the WebPKI within TLS. While such a desire for improved compression is natural, the external costs should not be underestimated or dismissed. I would rather have no compression than a biased dictionary, given these concerns.
