This patch is expected to significantly improve TLS handshake performance, and it replaces a C library that has been a frequent source of (occasionally security sensitive) crashes. We expected a small regression in binary size, and we have a plan to address this (Bug 1794045) which will ultimately bring the size down to or below that of the library we're replacing.
