Do you plan to change it for 2.24?

Let me elaborate...
Right now, both tcmalloc and jemalloc cannot link statically against glibc
2.24 and I'm trying to:
 - Make they link statically again.
 - Remove all references to __malloc_initialize_hook (even outdated source
   code comments).
 - Stop using all the other malloc hooks.
 - Improve documentation on this, so that we can provide an answer to the
   following open questions:
