Sorry, I don't understand what you are saying here.  Could you please
say it in simpler words?  What are "icon fonts"? and what do you mean
by "it can be removed"?

If we add such a variable, it will be opt-in behavior, so only users
who want it will get the behavior that you consider deficient.  It
will be then up to those users to decide whether the behavior is good
enough for them.  So I see no problem with such an option; we don't
have to like each and every optional behavior that is by default
turned off.
