Desuperheaters in a high performance house

Does anyone know if there are any guidelines for using desuperheaters with HPWHs and ducted mini-splits in a high performance house? I will have a 65 gallon HPWH in my basement near the location for the outside AC/HP unit. There will be a 2 ton ducted mini-split HP serving the main floor, as well as a wall mount 1 ton in a loft/office area.
Does a desuperheater make sense in such a home and do mini-splits work with this?
Thanks,

I'm not aware of any desuperheater solutions that are compatible with mini-splits.
A standalone heat pump water heater works fine in houses heated & cooled with mini-splits, taking a good chunk off the latent load in summer, adding some to the average (but not peak) heat load that needs to be covered by the mini-splits in winter.
