For (a bit) better security (to reduce buffer overflow impact in future), is it possible to compile PHP libraries (PHP 81 , 82 ) , ProFTPd with Stack Canary, PIE enabled ?
(Sorry, I am not sure any side effort.)
The binaries shipped from RPM ones contains Stack Canary and PIE enabled.

It seems that a fix was already integrated into new DirectAdmin versions on Ubuntu 22.04:
PHP: Everything is green except RW-RUNPATH.
pure-ftpd, Exim and Dovecot: Everything is green except RW-RUNPATH and Symbols.
Is it possible to strip the symbols by using the "strip" command?
