I wish them luck with the rewrite, but those sorts of rewrites are usually just replications of Apple's Copland. I suspect these sorts of rewrites are attempts at capturing the zeitgeist of younger developers.

OP is going to be in for a world of hurt trying to find a solution, there's a reason why all these libraries are in 'old PHP'. Most of the big companies have 'Appified' their APIs with calendars, and the old .ical etc formats are there for legacy support. So you need to create an app, delegate it permissions and then you've got a REST API to play with. If you've got the skill to do this, you'll have the skill to write a syncing script.
