(Tested on 1.19.2, all mods versions are also 1.19.2)

Because of just 1 slab returning when both are broken, I would not use this mod for a while until fixed (see the other issue I created about losing 1 slab). In the meantime, here is a list of unsupported mods to add:

Macaw's series of mods: it contains slabs, for example, Macaw's roofs, Macaw's Paths and Pavings etc. Breaking breaks both slabs and returns 1.
Undergarden double-slab blocks always break as 2 slabs.
L_Ender 's Cataclysm - both double-slab breaking with 1 slab returned
Let's do Vinery - both double-slab breaking with 2 slabs returned for wood and dirt slabs
Create mod series - certain mods breaking returns just 2 slabs (Create: things and misc, Create Deco, Create Alloyed, Create Confectionery, )
Blue Skies: Just 2 blocks returned both broken
Twilight Forest - same
Supplementaries - same
Oh the biomes you'll go - same
Quark: Azalea slab don't work (returns 2), most others do, looks like need an update here
Domum Ornamentum: Do not know the result because that mod also crashed in my case (even without your mod) in this situation when trying to break double-slab that is crafted using the architectury cutter. But probably worth to support too.

To add to the incompatibility list:
Majrusz's-Enchantments has an enchantment for tools called "Telekinesis" which makes blocks instantly go into your inventory when broken. Doubleslabs however just drop on the ground with this enchantment

to add to the incompatibility list for 1.20.1:
biomes o' plenty maple slabs and pine slabs
