Hi!
The support would consist of blacklisting stuff that isn't really mineable or should not be mineable.
https://mods.factorio.com/mod/Prospector
this one makes ores turn into depleted versions after they run out. After prospecting they become another type that is again mineable. Mining depot lists these depleted ores as being mineable but they aren't (and shouldn't).
https://mods.factorio.com/mod/vtk-deep-core-mining
This one adds two kinds of ore sources, patches that are left behind when regular ores are mined that take a special kind of miner to mine. Those should almost certainly be blacklisted. Other is very similar to SE core mining ones, deep core cracks. Those too require special miner but the mining drones still mine them. Should be blacklisted.
Currently playing with about 300 mods including those two mods I talked about, SE, deadlock's stacked mining, dirty mining and all of brevven the ore selection in the depot is a "bit" overwhelming :)

Example of what I get when searching for "iron" in that UI:

First three are the patches from prospecting, shouldn't be there.
Next three are from dirty mining and are for the vanilla + two legit types of iron ore that prospector mod generates. Those are fine.
Next three are for stacked mining of the vanilla+two prospecting types. Those are fine.
Last one on first line is the vanilla iron ore, fine.
Next two are depleted versions of the ores from prospecting, shouldn't be there.
Next two are the prospecting mod ores, fine.
Next is stacked vanilla, fine.
next two are stacked depleted ore from prospecting, shouldn't be there
next two are stacked prospector ore types, fine
Everything else are a combination of mod ores from special seams/core holes that should not be there.
In total out of the 35 types of iron only 12 should be there I think (vanilla + 2 prospecting ores. Stacked, dirty and stacked+dirty variants of all three).
Not quite sure how to handle things where another mod generates a new type of ore from a source that shouldn't be mineable. E.g all those depleted ores from dirty/stacked mining. Should those be blacklisted by your mod or by dirty/stacked mining mods, I don't know.
