Voyager has just announced that they support lemmy's spoilers now, so I wondered if this is planned to be included in Boost soon?

The Voyager dev also had this to say:

It was a huge undertaking, involving a few different packages and nearly one hundred unit tests in order to ensure proper parsing logic.

Also, I've published Voyager's spoiler plugin with AGPL-3.0, so any other FOSS lemmy app using Remark for markdown parsing can more easily add spoiler support :)
