The glibc 2.34 release really should have added a GLIBC_2.34 symbol to the dynamic loader. With it, we could move functions such as dlopen or pthread_key_create that work on process-global state into the dynamic loader (once we have fixed a longstanding issue with static linking). Without the GLIBC_2.34 symbol, yet another new symbol version would be needed because old glibc will fail to load binaries due to the missing symbol version in ld.so that newly linked programs will require.
