Jesus christ The limit is still there. It will always be there until they completely change how they handle FormIDs. FormIDs are 8bit strings, the leading two bits are used to indicate the source plugin. Starting at 00 and ending at FF. FF is reserved for items dynamically created in the game. Therefore there is a max of 255 individual plugins. Skyrim SE comes with 5. Skyrim.esm, Update.esm, Dawnguard.esm, Hearthfires.esm and Dragonborn.ESM, leaving 250 available for use by the player. This is not news. This has been known for ages. Please attempt to do a modicum of research. ANYONE who works with mods could have told you this.
