lemonldap-ng-fastcgi-server has a hard dependency on nginx
The lemonldap-ng-fastcgi-server package on Debian has a hard dependency on 'nginx | nginx-extras'. According to https://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps , 'The Depends field should be used if the depended-on package is required for the depending package to provide a significant amount of functionality.'
Do we consider that this package is tightly and absolutely coupled to nginx and unable to work / provide significant functionnality without it, or it is simply a generic fastcgi gateway primarily intended to work with nginx but usable with something else ? (in which case a Recommends: would be enough)
The main reason for this interrogation is that I see a good reason to use a Depends: (in a quick start / evaluation scenario, pulling nginx automatically is quite handy when you install the package) but also good reasons not to ( The package seems to run just fine without nginx running or even installed, and might even prove useful for other web servers or applications that would rather contact a fastcgi gateway to authenticate a user rather than firing up a complete Perl environment ).
