I'm using shairport-sync next to forked-daapd as AirPlay sink for multiroom audio from AirPlay sources like iPhones. That works pretty good as described for forked-daapd: http://ejurgensen.github.io/forked-daapd/#pipes-for-eg-multiroom-with-shairport-sync

The pipe output is already working perfectly, however the also documented metadata pipe is not created:
[root@itunes ~]# ls -al /daapd-data/music/Zuhause*
prw-r--r-- 1 shairport-sync shairport-sync 0 Jul 31 18:36 /daapd-data/music/Zuhause.AirPlay
[root@itunes ~]#

But it is configured in /etc/shairport-sync.conf:
pipe =
{
name = "/daapd-data/music/Zuhause.AirPlay";
};
metadata =
{
enabled = "yes";
include_cover_art = "yes";
pipe_name = "/daapd-data/music/Zuhause.AirPlay.metadata";
pipe_timeout = 60000;
};

According to upstream documentation (https://github.com/mikebrady/shairport-sync/blob/1dd0d828363ccc0ce41e61c36cce1c0bd6b7054a/README.md), adding the --with-metadata option to configure is required. This seems to be not present in the current PKGBUILD: https://git.archlinux.org/svntogit/community.git/tree/trunk/PKGBUILD?h=packages/shairport-sync&id=27a8ca37618dd85b4de8a7d72008112228bf878a

TL;DR: Would it be possible to add the --with-metadata option to configure in the PKGBUILD, or are there reasons against it? AFAIK, It needs no additional dependencies and pipe support is already built in.

Additional info:
* package version(s): 3.3.1-OpenSSL-Avahi-dns_sd-ALSA-pa-stdout-pipe-soxr-sysconfdir:/etc
* config and/or log files etc: relevant parts are already put in the description. Full is in attachment.

Steps to reproduce:
* configure metadata section in /etc/shairport-sync.conf as described (set a valid path for pipe_name)
* start shairport-sync
* no pipe is created
