ubuntu php alternatives

shouldn't all the php options be set manually to the OS's default php?
i've just installed a new standalone ispconfig server, ubuntu20.04, ispconfig 3.2.7p1. automated install.
install command used --use-php=7.4,8.0

double checking all the settings, php and php-cgi are manually set to 7.4, php-cgi-bin is auto (8.0), i also had another recent test install, where php-fpm.sock was also auto (/run/php/php8.0-fpm.sock)

Code:

root@test:/etc/alternatives# ls -l php*
lrwxrwxrwx 1 root root 15 Dec 14 15:53 php -> /usr/bin/php7.4
lrwxrwxrwx 1 root root 19 Dec 14 15:53 php-cgi -> /usr/bin/php-cgi7.4
lrwxrwxrwx 1 root root 23 Dec 14 15:53 php-cgi-bin -> /usr/lib/cgi-bin/php8.0
lrwxrwxrwx 1 root root 35 Dec 14 15:53 php-cgi.1.gz -> /usr/share/man/man1/php-cgi7.4.1.gz
lrwxrwxrwx 1 root root 24 Dec 15 15:02 php-fpm.sock -> /run/php/php7.4-fpm.sock
lrwxrwxrwx 1 root root 31 Dec 14 15:53 php.1.gz -> /usr/share/man/man1/php7.4.1.gz

Code:

root@test:/etc/alternatives# update-alternatives --config php

also, on a php related, but separate issue..
in jk_init.ini

Code:

[php]
comment = default php version and libraries
paths = /usr/bin/php
includesections = php_common, php7_3

shouldn't this last section be php7_4, at least on ubuntu 20.04?, i realize the debian and ubuntu installs use the same script, debian may still need to be 7_3.
also shouldn't php8.1 be added into this jailkit config and as a php install option for the automated installer?
