I spent a bit of time yesterday trying it out in a few different 
scenarios, and unless I contrived a test that ended up with a 
significant number of separate shell lines, it didn't have any 
noticeable performance wins, even against a version of pkgsrc prior to 
my winter 2022 performance work.  It's likely that the extra overhead of 
having to create lots of temporary files more than counteracts any 
benefits from fewer forks.

So yeh, no point considering this any further.
