Currently, the test suite doesn't read back these files.
No idea whether it might be useful to parse the log file in future versions.
I think at least the log file has to be deleted, otherwise it would
consume more and more disk space, and finally exceed the max. file size
on certain systems...
If the default location moves, the test suite might need to use a
different session name, e.g. _jtrts, to make conflicts with user
sessions less likely.

I frequently use john's bash completion.
I also use bash completion for other commands (git, make, etc.), and I
know magnum uses john's bash completion a lot.
(May be he's the only other user.)
If nothing else works, I can check the version string and implement
assumptions based on hard coded version numbers.
I already do that for incremental mode names, external mode names etc.
of core versions; for jumbo I can use --list=..
For jumbo versions, I could also parse --list=build-info output (and add
anything I might need, but may be that --list=build-info line is already
good enough:
$JOHN is ./
For core versions, I might assume JOHN_SYSTEMWIDE_EXEC if no pathname is
specified etc.
