[1.7.10] [Minetweaker] Why do Mekanism machines need NBT tags on input to match exactly?

Using Minetweaker and Technomancy I found that Mekanism machines are the only machines I have found so far, that need you to specify the exact item NBT tag for an input item if it has any NBT tag at all.*

All other machines, Vanilla, IC2, IE, TE, Fz, etc. just accept any NBT tag on the item, if you do not specify an NBT tag in the minetweaker recipe.

I really wonder why this is and if it could be changed.

Much appreciated!

*Technomancy semi-products have NBT Data to keep track of their previous processing steps.
I will post this on the MT Issue Tracker as well.

NBT is necessary for many Mekanism items to not be confused in recipes.

Energy cubes use NBT for differentiating between tiers. Factories use NBT for different recipe types. There's many other cases that require this kind of functionality.

Yet, no other mods seem to need this.
And why would an input item without any NBT not mean "this specific item with any NBT attached"?
