project is over 1year old now. has been up-to-date with all releases. project is Composer driven -- most modules are locked to specific versions. since update form 8.8.0 to 8.8.1 every merge is has been needed manual truncate of cache_discovery after regular Drush CR. this was noticed due to Content Editing was un-able to save new or updated any Node Type. also then same for saving terms, etc..
*Is occurring in merges that do not contain any module updates (or removals) nor any composer updates as well (regular bug fixes, enhancements..)
workaround has been custom drush command to do regular cache clear then truncate cache_discovery (triggered by hooks when merges are done).

It's likely this issue predates Contrib.social: some issue and comment data are missing.
I am wondering if we are seeing the same issue in 🐛 \RouteNotFoundException: Route "entity.node.vmd_preview_list" does not exist. Active , it seems that conditions exist that allow dynamically defined routes via "DeriverBase" classes to be passed over before the available plugins list is cached.
