You're removing support for something someone might want to use for no
clear gain.  The bar for doing that needs to be higher than just random
cleanup, it needs to actively bring some benefit that justifies the
cost.  If something is sitting there not getting in the way and is
potentially going to be helpful for something in the future then there
needs to be a positive reason to take it away.
