Hmm, one slight complication with `show_failures_in_pending_blocks?` is that it's the method called from base text formatter but we don't want it issuing a deprecation.  You could probably change it to use `RSpec.configuration.instance_variable_get(:@show_failures_in_pending_blocks)` which is a hack but bypasses the deprecation warning and I'm OK with since it's a temporary thing just in 2.99.
