Right less then 45 ( out of 100 in total ) that might have been 
applicable for migration

Right arguably upstream should never carry generators of anykind ( and 
at one point we will need to drop the legacy sysv initscript 
compatibility otherwise those legacy initscripts will never get migrated 
and their daemon be fixed either if applicable ) and beside the 
limitation that timer units suffer from, cron generators can create 
quite the surprise for administrators, especially on batch servers.

That said out of necessity ( It's easier to write a generator rather 
then go through the leg work and bureaucracy of dealing with 
distribution processes )  there has already been written by Dwayne Bent, 
Konstantin Stepanov, Daniel Schaal and Alexandre Detiste an 
"systemd-crontab" which includes crontab generator which can be found 
here [1]

But I urge distribution integrators to go the extra mile and rather 
migrate existing cron jobs for components that already depend on systemd 
and or are part of the core/base OS and might thus benefit from that 

I would have migrating all the relevant cron jobs in Fedora but I had 
enough due to certain corporate attitude towards the project, certain 
part of their employees and their behaviour and as a result of that in 
the end things turned out differently than I had planned or anticipated.

That work would have most likely covered everything that should have 
been migrated in Mageia,OpenSuse and Arch ( Debian is of a different 
Scale ) but you know shit happens and things go unfixed as an result of
