Legacy API Integrations

I received an email from Simplisafe informing me they were discontinuing legacy API Integrations.

"We are officially sunsetting SimpliSafe's legacy APIs. When these APIs are shut down, integrations relying on them will also stop functioning; we believe you may be using one of these integrations. SimpliSafe has not actively supported these legacy APIs since 2016. In order to prevent unsupported APIs from compromising the security of our customers, we have determined that it is time to discontinue them."

My questions:

1. 
   
2. Will I still be able to access my Simplisafe 2 system using the IOS app?
   
3. What is the effective date of this change?
   
4. Will this break integration though Homebridge plugins?
   
5. Do you have any plans to support Homekit with your current systems?
