Yes that has been available for some time.
in /etc/pulse/default.pa there is a line like:
load-module module-jackdbus-detect
Change it to:
load-module module-jackdbus-detect connect=no
And pulse will not auto connect. I have had this set on my system and a

jack session set up to just connect what I want.
The number of channels Pulse bridges has quite a large effect on cpu use.

I agree.
The pa-jack bridge is still in development, though I think it is not that

near the top of the list of priorities :) The channels=x parameter is in

git I am told, but not in the release packages I am aware of.
There is also some talk about moving the package system defaults to

/usr/share so that a distro can drop it's own config file into /etc/pulse

without over writing the package defaults. There is also ~/.config/pulse/

where a user could add this. Though to be honest I am not sure how.
