I’d say what you really want is a combination of the Doofer Device™.
And the ability to set a DSP Chain as a Default For All Tracks (including newly created ones.)
With possibly a couple of more options for GUI, such as knobs instead of sliders in the Mixer view…
Those are both separate ideas I would support and I believe would give you the functionality you want but the way you have presented it in this thread, even with the edited first post, don’t feel right to me.
EDIT: Actually there is on vital aspect to Channel Strips which the above solution would not provide! Namely Send and Return points for sending through effects that aren’t part of the standard DSP Chain. Not sure this could be fitted it with the above solution, you would need some visual separation between the channel strip and user-added effects and something to make it clear at what point this is happening. Unlike the Doofer Device I can only ever see you being able to have one such device per track and the normal (currently existing) DSP chain would sit between the Send and Return point.
