That should not be so bad, it is a private business not the government!
But we can have reasons to be doubtful.
5ed have been built during time of needs.
Now they are back on top, they can take it too cool, and mess things again!
They have concern now of large market scale, and expert players that we see here can be forget a bit.
I remember it but residum was too monolithic & still basically just GP. Finding xxxgp of residum was xxx gp of whatever residuum was for but finding 6 pounds of $specific general component or 100 pounds of a different one is going to be limited to their relevant umbrellas of spells rather than any spell. Having each spell have one off components listed only in the individual spell rather than having all spells drawing from a handful of generic pricy stuff makes it too difficult for anyone to realize on the spot without the gm sating "by the way guys that's used as the component in HINTHINTHINTTHISSPECIFICSPELLHINTHINTHINT". Think of the difference between giving players a large sum of diamonds everyone knows are needed for raise dead type spells & almost any other material components. Srttings like Eberron & Darksun could have their own lists & economies without needing to one off all the spells & such that way.
This is off the top of my head and I may expand later: Some of the things that I want.
