Flat world preset code: decoration not working properly, there are no plantation or ponds generating in any form.
E.g. 'minecraft:bedrock,2*minecraft:dirt,minecraft:grass_block;minecraft:plains;village,decoration'
This code would generate a flat world with 'decoration' in 1.15, but in 1.16 pre-releases, it won't.
The presets that do not work in 1.16 and higher are :
stronghold
village
biome_1
decoration (tree & grass)
lake
lava_lake
Probably other rules still

In 20w21a, structure options were removed from superflat presets. If you write 'decoration', click OK and then click Customize again, you will see the 'decoration' word having been removed.
They changed it to use the new import world settings button so those options are still there just you have to use json files for them.
Can confirm in :
1.16
1.16.1
1.16.2
1.16.3
1.16.4
1.16.5
1.17
1.17.1
and now snapshot 1.18 pre-release 6
The presets that do not work in 1.16 and higher are :
stronghold
village
biome_1
decoration (tree & grass)
lake
lava_lake
Probably other rules still
Yet modified block layers work well.
I add some screenshot so that you can have an overview.
Stronghold, ruined_portal and village are working, but lake, lava_lake, jungle_pyramid, desert_pyramid, decoration, oceanmonument, dungeon and biome_1 are not working. Please fix for 1.20🙏🙏🙏
Edit: They do work in previous versions but even when creating a world in a previous version where it works, then updating to the current version doesn't make it work. The new generating chuncks don't have the previously mentioned.
Heavily linked with - the "decoration" tag may have been removed intentionally, the preset "Overworld" does generate grass in 1.16 pre3 even without the tag.
