The current limit of 30 properties per event is extremely, well, limiting if your website/app has a lot of complex state that you want to keep track of.
I can understand if you want to limit your compute and/or database size on hosted Plausible by keeping a low custom property limit, but please make it a config option in self-hosted Plausible so that those who need more props can raise the limit without needing to fork the repository.
