Introduce puzzles for chess variants?

Can Lichess introduce puzzles with variants themes (for example, crazyhouse or horde) to help learn those variants better?

Since lichess generate most our puzzles from real games this would not be a difficult thing I guess

By the way, Pychess got many chess variant puzzles that they claim to be from Lichess.

Example:
www.pychess.org/puzzle/CmoBh (crazyhouse)
www.pychess.org/puzzle/dwdnI (atomic)

Are these puzzles collected and created by Lichess originally? If so, why are they not on Lichess any longer?
