Re: [Jmap] Proposal: split sharing mechanism from JMAP Calendars spec

Hi Neil,

the idea regarding more fine grained "capabilities" for the task feature 
stems from the purpose of using JMAP as an approach for data portability 
and/or also "modernizing" legacy groupware/task systems API's.

While, e.g., attendees/assignees or recurrences are a standard feature 
for calendars, in our observation the situation is quite different with 
task management. As one extreme, Google Tasks just supports a handful of 
task properties.

I would limit such capabilities to a handful of feature differences seen 
in existing task system. I do not see too much interrelation between 
those features.

For fostering an open ecosystem, it would be great if man task systems 
and task apps could adopt JMAP for Tasks. Without a "capabilities" 
mechanism however, this would certainly be inhibited.

Best,
Hans-Joerg
