I realize that, but I also realize that there are a number of
(commercial) products available that accomplish this. It should be
possible to simply act as an SSL server yourself and while the
certificates would be different (the proxy's) seen from the actual
client and server's perspective, at least it could work.

The alternatives for any company wanting some security is either
disable https entirely or find a way to inspect and filter the data.
I think you would find most wanting to still support https while not
exposing themselves needlessly.
