I think until and unless we have verifiers for the properties, and automatic (re)setting them for at least the common ones, it's all just wasted work. They don't provide any useful info whatsoever. The only useful ones are: PROP_cfg, PROP_rtl, PROP_trees (for adjusting what is dumped, arguably possible to check differently) and PROP_ssa (for remove_unused_locals). The rest is just snake oil.
