Removing sysutils/polkit dependency from sysutils/libudisks?

[Pau Amma]

Several months ago, someone (swills@ IIRC) asked me to look into 
removing the sysutils/polkit dependency from sysutils/libudisks which I 
maintain. I just had a chance to look at that request and it would 
require at least removing the udisksctl utility from the default options 
and possibly removing it from the build altogether. However, its 
presence in the default options was expressly requested in 
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=240138#c18 when I was 
initially porting libudisks. Is the request for removal still relevant? 
I think it was made with an eye toward removing sysutils/polkit 
altogether. If it is relevant, does it warrant removing udisksctl, which 
I found useful for port smoke testing and troubleshooting, in addition 
to the reasons for its presence listed in the Bugzilla comment linked 
above?
