I think Florent already has a situation that can be described as convoluted.
Whether this is more so only he can say.
I didn’t suggest the filter module to start with because it filters a buffer
through an external command which isn’t Florent’s use-case (which is just the
ability to call an external command). However I see, buried deeply in the docs,
under the heading "Special use case: \write18 with caching” there is the
ability to call a single command which would work.
Someone with better knowledge of the macro would need to explain how to adapt
the ’size’ key to Florent’s usage to enable the caching.
