Well it's a bit more subtle than that. Skipping slow tests was added right
before we introduced parallel execution to tempest ~5 years ago:
Note those are in separate testr jobs which we migrated to the full job a bit
later in that cycle. The full job back then ran using nose and ran things
serially. But back then we didn't actually have any tests tagged as slow. It was
more of a future proofing thing because we were planning to add a bunch of
really slow heat tests we didn't want to run on every commit to each project.
The slow tags were first added for heat tests which came later in the havana

It was changed in:

So there used to be an experimental queue tempest-all job which ran everything
in tempest, including the slow tests. I can't find it in the .zuul.yaml in the
tempest repo, so my assumption is that got dropped during the v3 migration.
I'm fine with adding a general purpose job for just running the slow tests to
the integrated gate if we think there is enough value from that. It's mostly
just a question of weighing the potential value from the increased coverage vs
the increased resource consumption for adding yet another job to the integrated
gate. Personally, I'm fine with that tradeoff.
