I think a version with all default dependencies should stay for new users. Experienced user have no problem install everything with a standalone or use a tar.gz.
But create additional packages like froxlor-webserver (depends on nginx or apache2) and so on, all features work
-> froxlor has froxlor-webserver + froxlor-mail ... as dependences
-> froxlor-standalone has no dependences as extra package without.
-> you can always suppress dependences.
If you install froxlor-webserver maybe apache is installed because mod-rewrite and over stuff is more supported by cms right now. If you want nginx simply install froxlor-webserver nginx.
PS: In 0.9.26 i have some \n in output in console.
