Definitely: I should have excised it when copy&pasting, sorry.
Those benchmarks only make sense individually and you need to know what
they do to interpret the results.

I encourage you to contribute it to elisp-benchmarks.
"All it takes" is a file which defines an `elb-relint-entry` function
whose execution takes a reasonable amount of time (I'd say more than 1s
but not too much more than 10s).

Of course, with Relint there's the extra issue that it involves
a package not included in Emacs.  For the SMIE test, I used `sm-c-mode`
by copying a snapshot of it into the `elisp-benchmark`, because the
intention was not to measure the performance of `sm-c-mode` but the
performance of SMIE.
