Yes, I make my modules for my personal needs in the first place (I own a LinnStrument and there wasn’t a MIDI/MPE2CV module that fits my needs, so I created my own). And I give my modules open source to the community.
The slews applied to the incoming MIDI data are there to avoid glitches when playing on an MPE controller (my module also applies slews on pitchbend and CC messages). All the MIDI/MPE modules I know so far are not designed to work with MIDI data drawn/entered in a DAW.
The VCV “MIDI to CV” module has an option to disable smoothing for pitch bend and CC1 messages:
What you may need is a module that gives you raw MIDI data. Unfortunately this doesn’t exist at the moment.
