No, it is not used indirectly. emacs_blocked_malloc is the only
function that uses malloc_hysteresis to set __malloc_extra_blocks.
And emacs_blocked_malloc is invoked only in the non-SYNC_INPUT code.

A nice property of removing the non-SYNC_INPUT code is that
we don't need to worry about cruft like that, because it's
not being used and we can remove it.
