note that i'm only trying to use this action because i cannot record an un-modified automation curve in REAPER due to the "return speed" function.

this "end of project" action isn't appropriate for use with AI, where the envelope does not exist outside the AI bounds. however, i hoped there would at least be an action version for "Automation: Write current values for all writing envelopes from cursor to end of AI"
of course, even actions like these make or a bad workflow when you're just trying to record an unmodified curve that does not return to the original value, like a lowpass filter that goes from open to closed and
does not return.
