generation_counter includes time spent on both JIT:ing expressions and tuple deforming which are configured independently via options jit_expressions and jit_tuple_deforming. As they are combined in the same counter it's not apparent what fraction of time the tuple deforming takes. This adds deform_counter dedicated to tuple deforming, which allows seeing more directly the influence jit_tuple_deforming is having on the query. The counter is exposed in EXPLAIN and pg_stat_statements bumpin pg_stat_statements to 1.11.
