I wanted to leave a note confirming that this work-around works like a charm.
And it is good to know that this is a confirmed #BUG that YoYo will be addressing, as I have my own extensions where I "hide" variables as extension macros/constants a lot.
Especially adding scripts in as extension macros (mygoogleorsteamID()), with the script holding the piece of semi-sensitive data.
Thank you for the update, YAL.
