Hmm, your analysis seems sound enough. We do call the setVariable
command on the cooker which I had expected to ensure the variable was
set appropriately without a reparse.

We can easily add a patch to trigger a reparse once IMAGE_FSTYPES is
changed, as we do with several of the other preference values.

Something like:
