This sounds very very odd?

Why ride the line? It'd take one major issue then you're way over you error budget?

For testing/simulations I can see why you'd introduce the errors.

My understanding is that they don't bring the service to exactly the SLO... To prevent overreliance on a service, it can be sufficient to introduce some level of failure, which may still be well above the SLO.

One major issue and you stop artificially inserting errors, which are inserted at a rate such that you could turn off the error inserted within some timely manner and still stay within budget.
