Biome Variant Mobs Should Drop Their Respective Blocks

If the title is confusing basically what I mean is.

-Husks should drop sand. You could add an extra variant of Husk for Badlands to drop red sand.
-Strays already drop tipped arrows.
-The Bogged should drop mud.
-Drowned should drop gravel.

 Simply adding this could fix the problem of not being able to renew sand and gravel without glitches which you could then fix without outrage from the community.
I think that mud is a good choice too because it may be renewable but it is not farmable in any way.
